Question

find the measure of an angle which is supplement of itself​

Answer 1

Answer:

90

Step-by-step explanation:

let number = x

x + x = 180

2x = 180

x = 90

Answer 2

let the angle supplement to itself be x

we know that

sum of supplement angles = 180

=> x + x = 180

=> 2x = 180

On dividing both sides by 2 , we get

2x / 2 = 180 / 2

=> x = 90

Thus required angle is 90...
