Question

Find the measure of the missing angle.
112°
a

Answer 1

68°

Explanation:

Given one of two angles of a linear pair is 112°, you want the measure of the other angle.

Linear pair

The angles of a linear pair are supplementary—their sum is 180°.

a +112° = 180°

a = 68° . . . . . . . . . subtract 112°

The measure of angle 'a' is 68°.
