5x=180°-45
x=135÷5
x=27
x is 27

Recall that two angles are complementary if the sum of their measures is 90 degrees°. find the measures of two complementary ang

Julli [10]

Let x represent the smaller angle. Then the larger one is 20+4x. Since they are complementary, their sum is 90. (All measures are degrees.)

90 = x + (20+4x)
90 = 5x +20
70 = 5x
14 = x

The smaller angle is 14°.
The larger angle is 76°.
