Question

an angle is equal to five times its supplement find the measure of the angle

Answer 1

let the angle be x

x=5(180-x)
x=900-5x
6x=900
x=150

Answer 2

Answer:

Let the supplement angle be x.

And the other angle will be five times its supplement.

Then, the angle will be 5 × x = 5x

Now,

5x + x = 180°

6x = 180°

x = 180°/6

x = 30°

Now,

5x = 5 × 30 = 150°
