Find the measure of the supplementary angle of $$138^\circ$$.


ANSWER

$$42^\circ$$


SOLUTION
Two angles are supplementary when they add upto form $$180^o$$.
Given, one angle $$= 138$$.
Let the supplement angle be $$x$$
Hence, $$x= 180-138$$ $$=42^o$$ 
Hence, supplementary angle of the following angle is $$42^o$$.
