Question

Find the measure of an angle whose complement is five times its measure

Answer 1

Let the angle be x. Then it's complement is 5x.
According to the question,

x+5x=90 degree {the sum of two complement angles is always 90 degree}
6x=90
x=90/6=15 degree

Hence if one angle is 15degree other one will be 5x=5×15=75 degree

Hope that helps you ✌️

Answer 2

Let 1 angel=x and the complement angle =5x

As per question

x+5x=90degree(as the sum of two angle=90)

6x=90

x=90/6=15 degree and the complement

angle =5x=5×15=75 (Ans)
