Question

If the supplement of an angle is two-third of itself. Determine the angle and its supplement.

Answer 1

Given that 

Supplementary of an angle = 2/3 of angle itself. 

The angle measured be ‘x’ say. 

Supplementary angle of x will be (180-x)^o

It is given that

Hence, supplement = 180 -108 = 72^o

Angle will be 108^o and its supplement will be 72^o .
