Find the angle which is equal to its supplement

Solution:

Supplementary angles are those angles that sum up to 180 degrees. 

Let the angle be 𝑥.

Therefore, the supplement of this angle will also be 𝑥.

We know that the sum of the measure of pair of supplementary angles is 180°.

𝑥 + 𝑥 = 180°.

2𝑥 = 180°.

𝑥 = 180°/2

𝑥 = 90°.

Thus, the angle which is equal to its supplement is 90°
