Question

an angle is four time of its complimentary angle. find the angle and it supplementary

Answer 1

4x+x=90
5x=90
x=90/5
x=18


Supplementary of 18° = 180-18
=162°

Answer 2

Step-by-step explanation:

Let the angle be x

We know that supplement of an angle = 180-x

Complement =90- x

Supplement = 4(complement)

180-x =4(90-x)

180-x= 360–4x

3x =180

x=60

Hence the angle is 60

Supplement =120; Complement = 30
