Question

find the angle which is equal to it's supplementary ​

Answer 1

Answer:

Let the angle be x, put x+x=180∘, and then find the value of x to solve the question. We have to find the angle which is equal to its supplement. Let the angle be x. Hence, the angle which is equal to its supplement is 90 degrees.

Have a good day ahead ☺☺❤❤

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°.
