Two angels are complementary. One angle is 18 degrees more than 2 times the other. Find the angles.

Two complementary angles = 90°

X = 18 + 2y

X + y = 90

Plug first equation into second

18 + 2y + y = 90

18 + 3y = 90

18 - 18 + 3y = 90 - 18

3 y = 72

3y/3 = 72/3

Y = 24

Plug y into 2nd formula

X + 24 = 90

X + 24 - 24 = 90 - 24

X = 66
