What are the properties of a diagonal of rhombus?
In a rhombus, diagonals bisect each other at right angles. Diagonals bisect the angles of a rhombus. The sum of two adjacent angles is equal to 180 degrees. You will get a rectangle when you join the midpoint of the sides.
Solution:
Given :
EJ = 24
∴ GJ = 24
∠FHG = 74°
∴ ∠EFH = 74° by alternate angle properties
Now, we know
FG² =FJ² + GJ² - 2FJ × GJ × cos(90) ------ diagonals of the rhombus are perpendicular to each other
Substitute FG = 25, GJ = 24, we get
25² = FJ² + 24² - 2FJ × GJ × cos(90)
FJ² = 49
∴FJ = 7
180 =∠GHJ +∠HGJ + ∠GJH ------ sum of all angles of a triangle is 180°
∴ ∠HGE = ∠HGJ = 180 - 90 - 74
∴ ∠HGE = 16°

please mark me brainlieset and click the stars i spent so long on this :>
Answer:
ZX = 3√2, XY =√10, YZ = 4, Perimeter of ΔXYZ = 14√5 units
Step-by-step explanation:
1. We can see that if we were to draw an altitude from vertex X to side ZY of this triangle, the length of this altitude would be: 3 units
2. The length of ZX can be determined through Pythagorean Theorem. If this altitude were to be called XW, it would be one of the legs of a mini triangle ZXW, along with leg ZW. ZW clearly = 3, thus ZX^2 = 3^2 + 3^2 = 18, and ZX = √18 units = 3√2.
3. The same thing can be applied to another "mini" triangle YXW. This triangle would have legs XW (altitude of the triangle ZXY) and YW. Knowing XW to have a length of 3 units, and YW to have length of 1 unit ⇒ XY^2 = XW^2 + YW^2 = 3^2 + 1^2, and XY = √10.
4. YZ is visualized to have a length of 4 units.
5. Knowing that ZX = 3√2, XY =√10, and YZ = 4 ⇒ Perimeter of ΔXYZ = ZX + XY + YZ = 3√2 + √10 + 4 = 14√5 units. To simplify this, it would be that the Perimeter of ΔXYZ = 14√5 units
ZX = 3√2, XY =√10, YZ = 4, Perimeter of ΔXYZ = 14√5 units
What are coordinates?A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.
1. We can see that if we were to draw an altitude from vertex X to side ZY of this triangle,
the length of this altitude would be: 3 units
2. The length of ZX can be determined through Pythagorean Theorem.
If this altitude were to be called XW, it would be one of the legs of a mini triangle ZXW, along with leg ZW.
ZW clearly = 3,
thus
[tex]ZX^2 = 3^2 + 3^2 = 18[/tex],
and ZX = √18 units = 3√2.
3. The same thing can be applied to another "mini" triangle YXW. This triangle would have legs XW (altitude of the triangle ZXY) and YW.
Knowing XW to have a length of 3 units, and YW to have a length of 1 unit [tex]= > XY^2 = XW^2 + YW^2 \\= > 3^2 + 1^2[/tex],
and XY = √10.
4. YZ is visualized to have a length of 4 units.
5. Knowing that
ZX = 3√2, XY =√10, and YZ = 4
⇒ Perimeter of ΔXYZ = ZX + XY + YZ
⇒ Perimeter of ΔXYZ = 3√2 + √10 + 4
⇒ Perimeter of ΔXYZ = 14√5 units.
To simplify this, it would be that the Perimeter of ΔXYZ = 14√5 units

Select all true statements if n || m.
Parallel lines M and N cut by two transversals, A B and B C. Along line M, three angles are labeled 2, 3, and 4, which together form a straight angle. Transversal A B forms two angles below line N, one labeled 20 degrees and the other labeled A. Together, these angles form a straight angle. Transversal B C forms two angles below line N, one labeled C and the other labeled 60 degrees. Together, these angles form a straight angle. Angle 1 is vertical to the 60-degree angle and is an alternate interior angle to angle 4. Together, angles 1, 3, and an unlabeled angle that is vertical to the 20-degree angle form a triangle between the two parallel lines.
A. m∠2 = 60°
B. m∠3 = 100°
C. m∠2 + m∠4 = 80°
D. m∠2 + m∠3 = 80°
E. m∠2 = 20°
Answer:
Hi, the correct answer is A) m∠2 = 60°.
let me put it in this way.
Step-by-step explanation:
Since parallel lines M and N are cut by transversals A B and B C, corresponding angles are formed. Corresponding angles are pairs of angles that are formed by intersecting lines and are on opposite sides of the transversal. In this case, angles 2 and C are corresponding angles, as are angles 3 and A.
We know that angles 2 and C form a straight angle along line M, and angles C and 60 degrees form a straight angle along line N. Since corresponding angles are congruent (have the same measure), this means that angle 2 must have the same measure as the 60-degree angle

The correct postulate is the Linear Pair postulate. It can be find out by the concept of supplementary angles.
What is supplementary angles?
Two angles are said to be supplementary if their sums total 180 degrees.
Linear Pair postulate: When two lines cross at one point, a linear pair of angles is created. If the angles follow the intersection of the two lines in a straight line, they are said to be linear. A linear pair's total angles are always equal to 180°.
Segment Addition Postulate: According to the segment addition postulate, if two points on a line segment, A and C, are given, a third point, B, will only be found on line segment AC if and only if the distances between the points satisfy the conditions of the equation AB + BC = AC. This option is not correct.
Vertical Angles: When two lines intersect each other then the angles made on the opposite sides of the intersection point is known as vertical angles and they give equal measurment. This option is not correct.
Addition Postulate states: The measure of an angle formed by two angles side by side is the sum of the measures of the two angles. This option is not correct.

suppose a researcher finds that the p-value of a test statistics is 0.08. which of the following significance levels gives you a chance of finding a statistically significant result? -0,01 -0,001 -0,1 -0,05
the best chance of finding a statistically significant result would be 0.1. This is because the p-value of 0.08 is less than the significance level of 0.1, but greater than the significance levels of 0.01, 0.001, and 0.05
The p-value of a test statistic is a measure of the probability of obtaining a result that is at least as extreme as the one observed, given that the null hypothesis is true. In other words, it is a measure of the strength of the evidence against the null hypothesis.
If the p-value of a test statistic is 0.08, it means that there is an 8% chance of obtaining a result at least as extreme as the one observed, given that the null hypothesis is true. This does not necessarily mean that the result is statistically significant at any particular significance level.
To determine whether a result is statistically significant, you need to compare the p-value to a predetermined significance level, also known as the alpha level. The alpha level is the probability of rejecting the null hypothesis when it is actually true (also known as a type I error).
If the p-value is less than the alpha level, then the result is considered statistically significant. For example, if the alpha level is set at 0.05, and the p-value of the test statistic is 0.03, then the result would be considered statistically significant.
In the case of the options you provided, the significance level that gives you the best chance of finding a statistically significant result would be 0.1. This is because the p-value of 0.08 is less than the significance level of 0.1, but greater than the significance levels of 0.01, 0.001, and 0.05.

Ana was washing dishes at the end of her shift at a restaurant. She washed 40 plates from 7:20 to 7:30.
When she finishes washing all the plates, her shift will end.
(a) If she started washing plates at 7:10 and ended at 7:35, estimate how many plates she washed in
total. Explain your reasoning.
(b) Write an equation to represent how many plates Ana has left to wash at a particular time after her
start at 7:10. Explain your reasoning.
Answer:
If Ana started at 7:20, ended at 7:38, and she washes 6 dishes per minute, than she has 108 dishes left to wash.
Step-by-step explanation:
Answer:
Step-by-step explanation:Answer: 138 plates are to be washed by her if she started at 7:15 and ends at 7:38, and the function will be f(x)=6x.
Step-by-step explanation:
Since we have given that
She washed 30 plates from 7:30 to 7:35,
That means in 5 minutes, the number of plates get washed here = 30
We need to find the number of plates from 7:15 to 7:38
First, we count the number of minutes
In 1 minute, the number of plates gets washed by her is given by
In 23 minutes, the number of plates gets washed by her is given by
The equation to represent how many plates Ana has left to wash at a particular time after her start at 7:15 is given by
Hence, 138 plates are to be washed by her if she started at 7:15 and ends at 7:38, and the function will be f(x)=6x.
The Chess Club wants to raise a total of $150 for a group trip.
They earn $1.25 for each box of pies they sell. They have
already made $16.25. Which equation could be used to find
how many more boxes of pies they must sell?
Answer:
Step-by-step explanation:
The number of boxes of pies that the Chess Club must sell to reach their goal of $150 can be represented by the variable x. We can create the following equation to represent this relationship:
1.25x + 16.25 = 150
To find the number of boxes of pies that the Chess Club must sell, we can solve this equation by subtracting 16.25 from both sides and then dividing both sides by 1.25:
1.25x = 150 - 16.25
1.25x = 133.75
x = 133.75 / 1.25
x = 107.
Therefore, the Chess Club must sell 107 more boxes of pies to reach their goal of $150.

The simplified form of the given expression is, [tex]((\frac{4}{9} )^-^4)^-^3(\frac{4}{9})^-^5 = (\frac{4}{9} )^7[/tex].
What is simplifying an expression?
To simplify an expression, create an equivalent expression without any terms that are similar. The expression will then be rewritten using the fewest terms possible.
Consider, the given expression,
[tex]((\frac{4}{9} )^-^4)^-^3(\frac{4}{9})^-^5[/tex]
To simplify this using the exponent rule:
[tex]((a)^b)^c = a^b^.^c[/tex]
⇒
[tex]((\frac{4}{9} )^-^4)^-^3(\frac{4}{9})^-^5 = (\frac{4}{9})^(^-^4^*^-^3)(\frac{4}{9})^-^5\\ ((\frac{4}{9} )^-^4)^-^3(\frac{4}{9})^-^5 = (\frac{4}{9})^1^2(\frac{4}{9} )^-^5[/tex]
Now use the exponent rule:
[tex]a^ba^c = a^(^b^+^c^)[/tex]
⇒
[tex]((\frac{4}{9} )^-^4)^-^3(\frac{4}{9})^-^5 = (\frac{4}{9} )^(^1^2^-^5^)\\((\frac{4}{9} )^-^4)^-^3(\frac{4}{9})^-^5 = (\frac{4}{9} )^7[/tex]
Hence, the simplified form of the given expression is, [tex]((\frac{4}{9} )^-^4)^-^3(\frac{4}{9})^-^5 = (\frac{4}{9} )^7[/tex].
