Question

The measure of an angle is 18 less than its complement. find the angle

Answer 1

let one be x

so other will be x+18

A/q

x+x+18= 90°
2x=90-18
x=72/2

x = 36

so other will be 54

Answer 2

HEYA!!!!!

YOUR ANSWER:

COMPLEMENTARY ANGLES: The angles which have their sum equal to 90°.

Let the angle be equal to x
It's complement = 90° - x

Then:
x = 90° - x - 18°
2x = 72°
x = 72°/2
x = 36°

SO,
x = 36°
And it's complement = 54°
