Angles algebra problem

Question

Two angles are supplementary if their sum is 180°. The larger angle measures eight degrees more than three times the measure of the smaller angle. If x represents the measure of the smaller angle and these two angles are supplementary, find the measure of each angle.

Answer 1

smaller angle = x

larger angle = 3x + 8

smaller angle + larger angle = 180°

x + 3x + 8 = 180

Solve for x.
