Question

Find the measure of an angle if its measure is 9 less than eight times the measure of its complement

Answer 1

Step-by-step explanation:

complementary angle = 90°

let one angle be = x

other angle = 8x - 9

x + 8x - 9 = 90

9x - 9 = 90

9x = 90 + 9

9x = 99

x = 99/9

x = 11

one angle = 11°

other angle = 8x - 9

= 8(11) - 9

= 88 - 9

= 79°

the complementary angles are 11° and 79°
