Question

In the drawing below, line h is parallel to line k.

What is the value of y?

A. 135

B. 15

C. 35

D. 145

Answer 1

D. 145

Explanation:

the lines are parallel, so you can set the two expressions equal to each other:

2x + 5 = 3x - 10

x - 10 = 5

x = 15

then plug in x to the angle next to y: 2(15) + 5 = 35°

180 - 35 = 145°
