Question

Find the measure of an angle which is equal to its supplement

Answer 1

Let the angle be x°

Now , since it is equal to it's supplement

i.e. x°+x° =180°

2x°=180°

x°=90°

Hence, 90 is the required angle

Answer 2

Answer: 90

Step-by-step explanation:

Let the angle be x

Therefore,

its suplement is 180-x

So

x = 180-x

x+x =180

2x=180

x= 90.
