What is meant by the included angle in SAS congruence theorem?
Answer:
The included angle means the angle between two sides. In other words it is the angle 'included between' two sides. In which pair of triangles pictured below could you use the Side Angle Side postulate (SAS) to prove the triangles are congruent? It is the only pair in which the angle is an included angle.

Find the value for X below
stop putting fake answers im reporting them all lol
Answer:
41
Step-by-step explanation:
Since a triangle is 180 degrees ans the triangle is on the right is equal to the triangle on the left, all you have to do is take 180 and subtract 86 and 53 from it to get 41. There's also the fact that the length of all the sides are the same so that can also mean that the angles are the same.
is this a domain or range?
please help :(
Step-by-step explanation:
it's a function.
the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.
the domain is (1,3,7,8)
the range is (2,4,6,9)

Answer: Only j = 2
============================================
Explanation:
Let's solve for j
[tex]\frac{96}{j} \ge 40\\\\96 \ge 40j\\\\\frac{96}{40} \ge j\\\\2.4 \ge j\\\\j \le 2.4[/tex]
In the second step, I multiplied both sides by j. If j is a positive number, then the inequality sign will not flip. All of the answer choices are positive numbers, so we don't have to worry about the inequality sign flipping.
The last step shows that j = 2.4 or j < 2.4
So j is 2.4 or smaller.
Of the list given to us, only j = 2 fits the description, since something like j = 8 is not 2.4 or smaller.
---------------------------
If j = 2, then,
[tex]\frac{96}{j} \ge 40\\\\\frac{96}{2} \ge 40\\\\48 \ge 40\\\\[/tex]
which is a true statement since 48 is larger than 40. This shows that j = 2 is a solution.
Something like j = 8 does not work because
[tex]\frac{96}{j} \ge 40\\\\\frac{96}{8} \ge 40\\\\12 \ge 40\\\\[/tex]
which is false because 12 is not equal to 40 or larger than 40. This means j = 8 is not a solution. You should find that j = 12 and j = 3 lead to similar false statements.
Of the list given, j = 2 is the only solution.
______________________________
1.) Solve using j = 12:Plug in 12: [tex]\frac{96}{12}[/tex] ≥ [tex]40[/tex]Divide 96 by 12: [tex]=8[/tex] Compare: [tex]8[/tex] ≥ [tex]40[/tex]
So this is False.
2.) Solve using j = 8:Plug in 8: [tex]\frac{96}{8}[/tex] ≥ [tex]40[/tex]Divide 96 by 8: [tex]=12[/tex] Compare: [tex]12[/tex] ≥ [tex]40[/tex]
So this is False.
3.) Solve using j = 2:Plug in 2: [tex]\frac{96}{2}[/tex] ≥ [tex]40[/tex] Divide 96 by 2: [tex]=48[/tex]Compare: [tex]48[/tex] ≥ [tex]40[/tex]So this is True.
4.) Solve using j = 3:Plug in 3: [tex]\frac{96}{3}[/tex] ≥ [tex]40[/tex]Divide 96 by 3: [tex]=32[/tex] Compare: [tex]32[/tex] ≥ [tex]40[/tex]So this is False.

Is LeBron James a more consistent scorer at home than on the road? During the 2008-2009 regular season at home, he has a mean of 25.35 points, with a standard deviation of 7.94 points in 40 games; while on the road, he had a mean of 31.46 points, with a standard deviation of 8.63 in 41 games.
a)Is 7.94 LeBron’s observed standard deviation at home or his true standard deviation at home? Explain.
b)State the hypotheses you would use to test if LeBron is more consistent at home.
c)Calculate the difference in standard deviations (road-home) and use this as the test statistic.
d)Describe how to simulate the distribution of the test statistic, assuming that LeBron is equally consistent at home and on the road.
e)Here are the results of 100 trials of the simulation. Describe what information is provided by the dotplot.
f)Based on the results of the simulation, estimate and interpret the p-value.

The inequality 5m − 7 > 16 holds true for all numbers than in the set {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}.
Answer:
{5, 6, 7, 8, 9, 10}
Step-by-step explanation:
Given the inequality
5m - 7 > 16
Add 7 to both sides
5m-7+7>16+7
5m>23
Divide both sides by 5
5m/5>23/5
m>4.6
Hence the value of m are the values in the set greater than 4.6 and they are {5, 6, 7, 8, 9, 10}
find the measure of the exterior angle in the following triangle DUE SOON I’LL GIVE BRAINLIEST
Answer:
A. 125
Step-by-step explanation:
the sum of the remote angles is equal to the exterior angle
90+35=125
Answer:
125°
Step-by-step explanation:
First find the interior angle. Sum of all the angles in a triangle is 180°.
180 - (90 + 35) = 55
A straight angle is also 180°
180 - 55 = 125

How do I solve this using substitution? Please write down the steps too.
6x+5y=-16
y=7x+5
Answer: x = -1 and y = -2
Step-by-step explanation:
You are given two expressions that have a relationship. There are two ways to solve this problem, but I will be going over the easy way. I'm assuming you know how to solve for one variable such as x? Well we can put the y varaible from the first equation in terms of x, from the second equation. Ill show you what I mean:
6x + 5(7x + 5) = -16
I replaced y in the first one in terms of x, so that we can solve just for x.
6x + 35x + 25 = -16
41x +25 = -16
41x = -41
x = -1
Now simply find y by plugging the now known x value into either equation
y = 7(-1) + 5
y = -2
Answer:
x = -1
y = -2
( -1, -2 )
Step-by-step explanation:
6x + 5y = -16
They gave us what "y" is and its....
y = 7x + 5
We substitute the "y" in the equation with this "y = 7x + 5
"
6x + 5y = -16
6x + 5(7x + 5) = -16
Now we need to use the distributive property (multiply what is in the parenthesis by "5")
6x + 5 * 7x + 5 * 5 = -16
6x + 35x + 25 = -16
Combine Like Terms ( 6x and 35x)
41x + 35 = -16
Subtract 25 on both sides
41x + 35 - 25 = -16 - 25
41x = -41
Divide by 41 on both sides to isolate the variable
41x/41 = -41/41
x = -1
Now that we have what "x" is (-1) we can use that to find out what "y" is.
y = 7x + 5
Substitute the x with -1
y = 7x + 5
y = 7(-1) + 5
y = -7 + 5
y = -2
x = -1
y = -2
( x, y )
( -1, -2 )

(−0.75x − 7) − (7.5x + 5.4) simplified
Answer:
[tex]-0.75x-7-7.5x-5.4=-8.25x-12.4[/tex]
Step-by-step explanation:
Given the expression
[tex]\left(-0.75x-7\right)-\left(7.5x+5.4\right)[/tex]
Remove parentheses: (-a) = -a
[tex]=-0.75x-7-\left(7.5x+5.4\right)[/tex]
As we know that: - (7.5x + 5.4) = -7.5 - 5.4
[tex]=-0.75x-7-7.5x-5.4[/tex]
Group like terms
[tex]=-0.75x-7.5x-7-5.4[/tex]
Add similar elements: -0.75x - 7.5x = -8.25x
[tex]=-8.25x-7-5.4[/tex]
Subtract the numbers: -7 - 5.4 = -12.4
[tex]=-8.25x-12.4[/tex]
Therefore, we conclude that:
[tex]-0.75x-7-7.5x-5.4=-8.25x-12.4[/tex]
