Question

The measure of an angle is three times the measure of a supplementary angle. what is the measure of each angle?

Answer 1

Supplementary angle = 180 degrees

angle 1 = x
angle 2 = 3x (three times the supplementary)

3x + x = 180
4x = 180
x = 45 degrees

angle 1 = 45 degrees
angle 2 = 135 degrees
