Question

Find the measure of the angle which is half of its supplementary angle? ​

Answer 1

Answer:

Therefore, the angle which is half of its supplement is of 60 degrees.

Answer 2

let x be the angle

its supplementary angle = 180⁰ - x

given that x = 1/2 of 180 - x

x = 180 - x

2

2x = 180 - x

2x + x = 180

3x = 180

x = 180/3

x = 60⁰
