Two angles are complementary. Their difference is 42°. Find the angles.
The smaller angle is
The larger angle is

Answer 1

24° and 66°

Explanation:

Complementary angles sum to 90°

let the larger angle be x then the smaller angle is x - 42 and their sum is

x + x - 42 = 90, that is

2x - 42 = 90 ( add 42 to both sides )

2x = 132 ( divide both sides by 2 )

x = 66 and x - 42 = 66 - 42 = 24

The smaller angle is 24° and the larger angle is 66°

Answer 2

x+y =90

x-y=42

2x=132

x=66

y=24
