The angle measure of a triangle is shown in the diagram.
what is the value of x?
A. 13
B. 20
C. 5
D. 12
Answers
All of the angles in this triangle add to give 180 degrees.
So set the sum of every angle = 180
180 = 95 + 3x+4 + 4X-3
To solve this you want x by itself so bring 95 to the other side by subtracting it. Add the 3x and 4X. Add 4 and -3.
85 = 7x + 1
Subtract the 1 to isolate x
84 = 7x
Divide by 7
X = 84/7
To see if it is A, B, C, D plug in the value and see if it adds up to 180

Find the distance between the points (-15,3) and (-9,8).
Answers

[tex]\\ \sf\longmapsto \sqrt{36+25}[/tex]
[tex]\\ \sf\longmapsto \sqrt{61}[/tex]
[tex]\\ \sf\longmapsto 7.32units[/tex]
Given info:- Find the distance between the points (-15,3) and (-9,8).
Explanation:-
Distance formulae:
Distance = √{(x₂ - x₁)² + (y₂ - y₁)²}
Let's figure out the distance between two points A = (-15,3) and B = (-9,8).
From those points,
x₁ = -15
x₂ = -9
y₁ = 3
y₂ = 8
Using them in the formula,
Distance btw AB = √[{(-9 - (-15)}² + (8 - 3)²]
= √[(-9 + 15)² + (8 - 3)²]
= √[(6)² + (5)²]
= √[(6*6) + (5*5)]
= √[36 + 25]
= √[61] Units.
Therefore, the distance between A(-25,3) and B(-9,8) is √(61) units.

Chris rented a truck for one day. There was a base fee of $14.99, and there was an additional charge of 75 cents for each mile driven. Chris had to pay
$167.24 when he returned the truck. For how many miles did he drive the truck?
M miles
Answers
Answer:
Chris drove the truck 203 miles.
Step-by-step explanation
So, first I subtracted the base free cost of the amount he paid and got $152.25. Then, I divided $152.25/0.75 and got 203. S0, that's how I got the answer. I subtracted the base free because we know he had to pay that initially and then I just divided the rest of the money he had to pay by 0.75 because he was charge 0.75 per mile driven.
Find two numbers x and y with a sum of 200 and a difference of 82
Answers

[tex]x=200-y[/tex]
Since the difference is 82,
[tex]x-y=82[/tex]
Substitute x in:

Here’s the question
W+2=12
Pls explain
Answers
Answer:
w = 10
Step-by-step explanation:
To find the value of w, you need to isolate w on one side.
You can start by subtracting 2 from both sides. What you do to one side of the equation, you have to do to both.
12 - 2 = 10
So now w is isolated and is equal to 10.
w = 10
You can check your work by replacing w with 10 in the equation.
10 + 2 = 12

Directions: find x so that L || M. state the converse used
Answers
Answer:
8. x=6; supplementary consecutive interior angles
10. x = 4; no applicable theorem
Step-by-step explanation:
8.The marked angles are "consecutive interior" angles. When their sum is 180°, the lines l and m will be parallel.
(7x -15) +(24x +9) = 180
31x = 186
x = 6
Consecutive interior angles being supplementary will make the lines parallel.
__
10.The sum of the remote interior angles of a triangle is equal to the exterior angle:
28x = 48 +16x
12x = 48
x = 4
The above relation holds regardless of whether line l is parallel to line m. There is no applicable theorem or converse.
_____
Additional comment
Adding the marking shown in the attachment would make the converse of the alternate interior angles theorem applicable to problem 10.

Use the slope formula to fond the slope of the line that passes through the two points.
(13, -2) and (3, -2)
Answers
Answer:
Step-by-step explanation:
Notice that the y-component is the same, -2, in these two points. That means y does not change as x changes, and therefore we conclude that the slope of the line connecting the two points is m = rise / run = 0.
-2 - (-2)
Alternatively, use m = -------------- = 0

The value of the slope in question is zero: m = 0

They have the same range.
Answers
Answer:
C.They have the same y-intercept.
Step-by-step explanation:
Edge 2021
The conclusion about the two functions is (c) they have the same y-intercept.
What are functions?Functions are used to represent equation, graphs and tables
The equation of the function is given as:
[tex]f(x) = (x + 4)^2[/tex]
Set x = 0, to calculate the y-intercept
[tex]f(0) = (0 + 4)^2[/tex]
Evaluate
[tex]f(0) = 16[/tex]
From the complete question, the graph crosses the y-axis at y = 16
This means that both functions have the same y-intercept
Hence, the true statement about the functions is (c) they have the same y-intercept.
