An angle measures 15 degrees more than its complement. Find the measures of the two angles
kap26 [50]

Answer:

The first angle is 37.5° and the second would be 52.5°

Step-by-step explanation:

Angles are complementary when their sums add up to 90°.

x+(x+15) = 90\\x+x+15=90\\x+x=75\\x=37.5

The first angle is 37.5° and the second would be 52.5°, after we plug in x.
