Question

Find the angle which is twice it's supplement?

Answer 1

Answer:

The angle is 120°

Step-by-step explanation:

Let both the angles be 2x and x.

The sum of both the angles is 180°

So, 2x + 3x = 180

3x = 180

x = 180/3

x = 60

Hence, both the angles are = 2x = 120°

x = 60°

This implies that the angle twice it's supplement is 120°

Answer 2

Answer:

120 ,60

Step-by-step explanation:

let ,

the angle be x

the second angle is 2x

the sum of supplementary angles is

180

So,

x+2x=180

3x=180

x=60

one angle is 60

another angle is 120
