Question

The measure of two complementary angles are in the ratio 1:4. What are the degree measures of the two angles ?

Answer 1

18,72

Explanation:

Complementary angles add to 90 degrees

Multiply the ratio by x

1x+4x = 90

Combine like terms

5x = 90

divide by 5

5x/5 = 90/5

x =18

The first angle is 18 degrees

4*18 =72

The second angle is 72 degrees
