Question

One angle is four times its complement. Find the two
angles​

Answer 1

Let one angle be x and the other angle = 4x

The two angles are complementary:

x + 4x = 90

Combine like terms:

5x = 90

Divide both sides by 5:

x = 18

Smaller angle = x = 18°

Larger angle = 4x = 4(18) = 72°

Answer: The two angles are 18 and 72
