The figure shows two intersecting lines and the measures of the resulting angles.

what is the value of y?

y= 114

Step-by-step explanation:

1) (4x+ 2x- 12+ 20)=180

First find x (22)

2) (2x+20)+y=180

Plug in x

3) y=114

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
