Question

The measure of an angle is 78 less than the measure or its complement.What is the measure of the angle

Answer 1

84°

Explanation:

2 complementary angles sum to 90°

let x be the angle then complement = x - 78, hence

x + x - 78 = 90 ( add 78 to both sides )

2x = 168 ( divide both sides by 2 )

x = 84

hence the angle is 84°
