Question

An angle is 5more than one-forth of its supplement .Find the measure of both the supplementary angles

Answer 1

Let the 1st angle be x and its supplement will be 180-x

According to the question,
x= 180-x/4 +5

x= (180-x + 20)/ 4
4x = 200-x
5x=200
x=40°

And 180-x is 180-40= 140°

The the required angles are 40° and 140°

HOPE THIS HELPS YOU:)

Answer 2

let its supplment is ₓ then the angle is according to the question x×1÷4+5

so x+x÷4+5=180

OR,X+(X +20)BY4=180

OR4X+X+20=180×4

5X+20=720

OR,5X=720-20

ORX=700BY 5=140° AND OTHER ANGLE IS 180-40=40
