Mathematics

 Find the measure of the supplementary angle pair of 138$$^o$$. (in degrees)


ANSWER

42


SOLUTION
Supplementary angles are two angles with a sum of $$180^o.$$
Measure of one supplementary angle is $$138^o.$$
$$\Rightarrow$$  Measure of other supplementary angle $$= 180^o-138^o$$
                                                                         $$=42^o.$$
