Recall that two angles are complementary if the sum of their measures is​ 90°. Find the measures of two complementary angles if one angle is four times the other angle

Question

what is the smaller angle?

Smaller angle = ___

Answer 1

Let x=smaller angle

Let 4x=larger angle

smaller angle + larger angle = 90

x+4x=90 Combine like terms

5x=90 Divide both sides by 5

x=18°
