Question

Find the value of 'X' also please explain causes I'm confused.

Answer 1

They have the same angle so set them equal to each other.

135=2x-3
+3. +3
---------------
138=2x
----- -----
2. 2
------------
69=x

Answer 2

Since the two lines are parallel and they are both being bisected by the same line, then the resulting bisected angles are the same.

To solve for x you will set 2x - 3 = 135, since both angle measures are the same.

2x - 3 = 135

2x = 138

x = 69
