Answer:
x=26
Step-by-step explanation:
let take the 3rd angle of the triangle y
2x + 76 + y = 180 ( angle sum property)
y = 180 ‐ 76 ‐ 2x
y = 104 ‐ 2x
5x ‐ 2 + y = 180 ( linear pair)
5x‐2+104‐2x = 180 ( y = 104 ‐ 2x)
3x+102=180
3x=180‐102
x=78/3
x=26

Answer:
y = -0.5x -2
Step-by-step explanation:
We have to find a line perpendicular to the line y = -2x -3.
Let the required line will have slope m so ,
-2m = 1
m = -0.5.
So, the required line will have the slope -0.5.
Now, let the line be y = -0.5x + c.
This line is passing through (-2,-1), So putting this point in the line we will get
-1 = 1 + c
c = -2 .
So, the required line is
y = -0.5x -2.
