Answer:
x ≈ 50.8°
Step-by-step explanation:
Using the sine ratio in the right triangle
sin x =
=
=
, then
x =
(
) ≈ 50.8° ( to the nearest tenth )
7. (1,2),(0,-1)
slope = (-1 - 2) / (0 - 1) = -3/-1 = 3 <==
8. (-1,0),(1,-1)
slope = (-1 - 0) / (1 - (-1) = -1 / 2 <==
45°. I’m not sure what the relationship is but I think it’s linear pair ?
Answer:
10x-17
Step-by-step explanation:
perimeter=a+b+c
p=(5x-7)+(3x-4)+(2x-6)=10x-17
Given:
Graph is given.
Two given points are:
![(0,4)\text{ and (}2,-2)](https://tex.z-dn.net/?f=%280%2C4%29%5Ctext%7B%20and%20%28%7D2%2C-2%29)
To find: Slope intercept equation
Formula :
![\frac{y-y_1}{y_2-y_1}=\frac{x-x_1}{x_2-x_1}](https://tex.z-dn.net/?f=%5Cfrac%7By-y_1%7D%7By_2-y_1%7D%3D%5Cfrac%7Bx-x_1%7D%7Bx_2-x_1%7D)
Explanation:
The equation of the line is
![\begin{gathered} \frac{y-4}{-2-4}=\frac{x-0}{2-0} \\ \frac{y-4}{-6}=\frac{x}{2} \\ \frac{y-4}{-3}=x \\ y-4=-3x \\ y=-3x+4 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Cfrac%7By-4%7D%7B-2-4%7D%3D%5Cfrac%7Bx-0%7D%7B2-0%7D%20%5C%5C%20%5Cfrac%7By-4%7D%7B-6%7D%3D%5Cfrac%7Bx%7D%7B2%7D%20%5C%5C%20%5Cfrac%7By-4%7D%7B-3%7D%3Dx%20%5C%5C%20y-4%3D-3x%20%5C%5C%20y%3D-3x%2B4%20%5Cend%7Bgathered%7D)
Option B is the final answer.
