Question

Find the magnitude of an angle which is 2/3 of it's supplement?

Answer 1

Step-by-step explanation:

let the first angle be x, then other angle=2x/3

and x+2x/3=180

5x/3=180

x=108

therefore other angle= 108*2/3=72

Answer 2

Step-by-step explanation:

2x÷3+x =180

5x÷3=180

x=108

108*2/3 = 72
