Question

Two angles are complementary. One angle measures 30 degrees less than five times the measure of the other angle.

Find the measure of each angle.
solve using systems of equations

Answer 1

Answer: 20° and 70°

Explanation:

Complementary means they add up to 90 degrees

x+y=90

x=5y-30

Substitute:

6y-30=90

6y=120

y=20

x=70
