Question

what angle is equal to its supplement​

Answer 1

Answer:

the angle is equal to it's supplement=

180°

Answer 2

Step-by-step explanation:

Let the measure of the angle be x

∴ The measure of its supplement angle = 180° - x.

Since angle is equal to its supplement

∴ x = 180° - x

→ x + x = 180°

→ 2x = 180°

→ x = 180° ÷ 2

→ x = 90°

Hence, the required angle is 90°.
