Answer:

the angle which is equal to its supplement is 90°

Step-by-step explanation:

x=180°-x

2x=180°

x=90°

Answer 2

Answer:

b) 90°

Step-by-step explanation:

An supplementary angle is either of two angles whose sum is 180°.

So lets solve this question according to the above statement.

Let its one angle be x

As we want both the angles to be equal so the other angle will also be x.

so the equation will be x + x = 180°

= 2 x = 180°

x = 180° / 2

x = 90°

hope this helps!!!
