LET X BE THE SUPPLEMENT

THERE FORE THE ANGLE =2X/3

THEREFORE

2X/3+X=180

5X/2=180

5X=360

X=360/5=72

THEREFORE THE ANGLE IS 180-72=108 DEGREE

I HOPE THIS HELPS...

Let one angle be X then its supplementary angle is 2X/3

X+2X/3=180

5X/3=180

X=108

supplementay = 2 x 108/3=72

X+2X/3=180

5X/3=180

X=108

supplementay = 2 x 108/3=72
