Question

The measure of supplement of an angle is equal to the twice the measure of the

angle. What is the measure in degrees, of the compliment of the angle ?

Answer 1

30°

Explanation:

Let 'a' represent the measure of the angle.

The relationship between the angle (a) and its supplement (2a) is ...

a +2a = 180°

a = 180°/3 = 60°

Then the complement of the angle is ...

90° -a = 90° -60° = 30° . . . . the complement of the angle
