Question

20. Two angles form a linear pair. The measure of one
angle is the measure of the other angle.

Answer 1

x+x=180

Each angle is 90 degrees

Explanation:

A linear pair add to 180 degrees

If one angle is the measure of the other angle, they are the same

x+x=180

2x = 180

Divide each side by 2

2x/2 = 190/2

x = 90

Each angle is 90 degrees
