The measure of two complementary angles are in the ratio 1 : 4. what are the degree measures of the two angles?
a 18° and 72°
b. 22.5° and 67.5°
c. 36° and 144°
d. 45° and 135°

A 18° and 72°

Step-by-step explanation:

As you know, the sum of two complementary angles = 90

The ratio 1 : 4 = 1 + 4 = 5

So 90/5 = 18

1 x 18 = 18

4 x 18 = 72

The two complementary angles are  18° and 72°

Answer

A 18° and 72°
