# Find the angle which is equal to its complement

**Solution:**

Complementary angles are those angles that add up to 90 degrees.

Let the angle be 𝑥.

Therefore, the complement of this angle will also be 𝑥. [Since, its given that the angle is equal to its complement]

We know that the sum of the measure of pair of complementary angles is 90°.

𝑥 + 𝑥 = 90°.

2𝑥 = 90°.

𝑥 = 90°/ 2

𝑥 = 45°.

Thus, the angle which is equal to its complement is 45°.
