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

Given that,

Supplement = of angle itself

Let the angle be x

Therefore,

Supplement = (180^o – x)

According to the question

(180^o – x) =

5x = 540^o

x = 108^o

Hence, supplement = 72^o

Therefore, angle will be 108^o and its supplement will be 72^o.
