Question

Q16-Find the magnitude of an angle which is equal to its supplement.​

Answer 1

Step-by-step explanation:

Given:-

an angle which is equal to its supplement.

To find:-

Find the magnitude of an angle which is equal to its supplement.

Solution:-

Let the angle be X°

We know that the supplementry angle of X°

=180°-X°

Given that

the angle is equal to its supplement

=>X°=180°-X°

=>X°+X°=180°

=>2X°=180°

=>X°=180°/2

=>X°=90°

Answer:-

The required angle =90°

Supplementary angles:-

The sum of two angles is equal to 180° then the angles are called supplementary angles
