Lines and Angles | Exercise 5.1

So again supplement angles are the angles that add up to 180. So 180. So for example, if an angle is 180, so 180 minus X will be equal to the supplement of X.

Answer 2

Step-by-step explanation:

Let the required angle be x°

Therefore, it's supplement = (180-x)°

Now, x = 180-x

= x+x = 180

= 2x = 180°

Therefore x=180/2

= 90°
