Find the measure of an angle which is complimentary of itself.1. 40° 2. 45° 3. 30° 4. 50°

Answer» Correct Answer - Option 2 : 45°

Complimentary angles: When the sum of the measures of the two angles is 90°, the angles are called Complimentary angles.

Calculation:

Let the measure of one angle be x°

Then other angle = 90° - x

⇒ x° = 90° - x°

2x° = 90°

∴ x = 45°
