Question

Find the angle which is twice of its supplement

Answer 1

Let one supplement angle=x

Twice of supplement angle=2x

so we know two supplement angle =180°

Then

x+2x=180°

3x=180°

x=180÷3=60°

2×60=120°

Answer 2

hey buddy,

let the one supplement angel be x

and second one will be 2x

we know that,

sum of supplement angels = 180°

therefore,

x+2x = 180

3x = 180

x = 180÷3

x = 60

one supplement angel = x = 60°

and the second one = 2x =2*60 = 120°

hope it helps you

thank you
