Question

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

fourfour

times the other angle.

Answer 1

x = 4y

x+y = 90

4y+y = 90

5y = 90

y = 90/5 = 18 degrees for one angle

x = 4(18) = 72 degrees for the other angle
