Can yaal help me Find the value of x
Answer:
C
Step-by-step explanation:
the ratios of corresponding sides are in proportion
that is the outer triangle and the inner triangle
[tex]\frac{x}{30}[/tex] = [tex]\frac{88}{44}[/tex] = 2 ( multiply both sides by 30 to clear the fraction )
x = 30 × 2 = 60
Answer:
C. 60
Step-by-step explanation:
I just saw that 44 + 44 equals 88 and compared those two sides, I knew it couldn't be 88, so that's out. Then, I saw that the side, 21 + 21, was shorter than the unknown side and that ruled out 42 and 30. 60 is the only one that is left and makes sense.
Given the midpoint B (-41, 23), create 2 different set of end points that don’t have the same x or y value of the midpoint. Verify your points by solving for the midpoint and identify them as points G and H. Show your work to prove your answer
can someone pleas help
Using the mid-point concept, the set of points that has midpoint B(-41,23) is: G(10,10) and H(-92,36).
What is the mid-point concept?The mid-point between two points is the halfway point between them, and is found using the mean of the coordinates.
In this problem, we have that:
The mid-point is B(-41,23).The other points are G(10,10) and H(x,y).Hence the coordinates of H are found as follows:
[tex]-41 = \frac{10 + x}{2}[/tex]
10 + x = -82.
x = -92.
[tex]23 = \frac{10 + y}{2}[/tex]
10 + y = 46.

The given linear equation has one solution: (-0.6, 1.6). The correct option is the second option one solution: (-0.6, 1.6)
Solving system of linear equationsFrom the question, we are to determine the number of solutions the given linear equation has
The given system of equations is
y = 2/3x+ 2 ---------- (1)
6x - 4y = -10 ---------- (2)
Substitute equation (1) into equation (2)

Hello !
Answer:
Step-by-step explanation:
Pythagorean Theorem : a² + b² = c² ⇔ b² = c² - a²
Here, we have a = 4 and c = 6 so :
b² = 6² - 4²
⇔ b² = 36 - 16
⇔b² = 20
⇔ b = √20 (and not b= -√20 because b ≥ 0)
Answer:
b = [tex]\sqrt{20}[/tex]
Step-by-step explanation:
Using the Pythagorean Theorem:
6² = 4² + b²
⇒ b² = 6² - 4²
⇒ b = [tex]\sqrt{6^2 - 4^2}[/tex]
⇒ b = [tex]\sqrt{36 - 16}[/tex]
⇒ b = [tex]\sqrt{20}[/tex]

How many degrees is angle X?
How many degrees is arc ZY?
How many degrees is arc XY?
(Picture is below)
Answer:
X = 70°arc ZY = 140°arc XY = 82°Step-by-step explanation:
The angle sum theorem helps you compute the angle inside the triangle. The inscribed angle theorem helps you compute the arc measures outside the triangle.
TheoremsThe Angle Sum theorem tells you the sum of angles in a triangle is 180°. That lets you write the equation ...
X +Y +Z = 180°
X +69° +41° = 180°
The Inscribed Angle theorem tells you an inscribed angle has half the measure of the central angle subtending the same arc. The arc and the central angle have the same measure: twice that of the inscribed angle.
arc ZY = 2×∠X
arc XY = 2×∠Z
SolutionsUsing the equations we wrote describing the relationships of the unknowns to the known information, we find ...
X = 180° -110° = 70°
arc ZY = 2×70° = 140°
arc XY = 2×41° = 82°
Answer:Angle x=70°
Step-by-step explanation:interior angles add up to 180° so we add 41° and 69°. After addition,you minus from 180° and you get 70°

The largest number of different whole numbers that can be on Zoltan's list is 999
How to determine the largest number?The condition is given as:
Number = 1/3 of another number
Or
Number = 3 times another number
This means that the list consists of multiples of 3
The largest multiple of 3 less than 1000 is 999

The figure shows a circle circumscribed around a triangle.
Triangle U T V is inscribed within a circle. A point is at the center of the triangle. Lines are drawn from the points of the triangle to the point in the middle. Lines are drawn from the point in the middle to the sides of the triangle to form right angles.
What is constructed first when creating the circle?
perpendicular segments to the vertices of the triangle
perpendicular bisectors of the sides of the triangle
angle bisectors of each angle of the triangle
the incenter of the triangle
Option B is right perpendicular bisectors of the sides of the triangle
What circumcircle?If we draw a circle through all the vertices of a triangle then the circle obtained is the circumcircle of the given triangle. We have in a triangle there are some properties inherent.
One is the perpendicular bisectors of all sides are concurrent. These three concur at a point called the circumcentre of the triangle.
When we draw a perpendicular bisector for a side AB, we get that all points on the perpendicular bisector are equidistant from A and B.
When we take the point of intersection of the perpendicular bisector of AB and BC, we have the intersecting point S(say) is equidistant from A and B and also from B and C
In short, this is equidistant from all 3 vertices and hence is the centre of the circumcircle of triangle ABC
Therefore Option B is right perpendicular bisectors of the sides of the triangle.

Why are there two solutions for the equation |6+y| = 2?
Explain.
Answer:
y=-4 and y=-8
Step-by-step explanation:
When you have an absolute value around something, you can remove it, expect it's like a square root, it's going to be a [tex]\pm[/tex]. Because 6+y could've been -2 and the absolute value just made it positive 2
So set 6+y equal to -2 and 2 to find the two solutions:
6+y = 2
y = -4
6+y = -2
y = -8
Hey there!
YOUR EQUATION: |6 + y| = 2
CONVERT THAT TO:
y + 6 = 2 OR y + 6 = -2
FIRST let’s solve for: y + 6 = 2
y + 6 = 2
SUBTRACT 6 to BOTH SIDES
y = 6 - 6 = 2 - 6
SIMPLIFY THAT!
y = 2 - 6
y = -4
Possible solution #1: y = -4
LASTLY let’s solve for: y + 6 = -2
y + 6 = -2
SUBTRACT 6 to BOTH SIDES
y + 6 - 6 = -2 - 6
SIMPLIFY THAT AS WELL!
y = -2 - 6
y = -8
Possible solution #2. y = -8
Therefore, your answer should be:
y = -4 or y = -8

If 7 litres of petrol will last 23 minutes in Dave's car, then how long will 25 litres last? Give your answer to the closest minute.
Answer:
25 liters will last 82 minutes.
Step-by-step explanation:
All you have to do is divide 23 by 7 to get the minutes per liter.
This will get 3.285714285714286.
Next you multiply 3.285714285714286 by 25 and you get 82.14285714285714.
But since we need to round the answer by the closest minute the answer would be 82 minutes.

What are trigonometric relations?Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles
The six trigonometric functions are sin , cos , tan , cosec , sec and cot
Let the angle be θ , such that
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
tan θ = sin θ / cos θ
cosec θ = 1/sin θ
sec θ = 1/cos θ
cot θ = 1/tan θ
Given data ,
Let the triangle be represented as ΔABC
Now , the measure of ∠BAC = 30°
The adjacent side of the triangle AC = √3 units
The hypotenuse of the triangle AB = 2 units
So , from the trigonometric relations
cos θ = adjacent / hypotenuse
On simplifying , we get
cos ( 30 )° = √3/2
Therefore , the measure of cos ( 30 )° = √3/2
Hence , the trigonometric relation is cos ( 30 )° = √3/2
