Question

Find the angle which is equal to its supplement.

Answer 1

Let \(x\) be two equal angles of its supplement.
Therefore, \(x + x = 180\degree\) [Supplementary angles]
\(\Rightarrow 2x = 180\)
\(\Rightarrow x = \frac{180\degree}{2}= 90\degree\)

Thus, \(90\degree\) is equal to its supplement.
