Question

Find the angle which is twice its supplement?

Answer 1

Heya user ,
Here is your answer !!

Let the angle be x° .
So , its supplement is ( 180 - x )°

ATQ ,
x = 2 ( 180 - x )
=> x = 360 - 2x
=> 3x = 360
=> x = 120

So , the angle which is twice its supplement is 120° .

Hope it helps you !!

Answer 2

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°
