Given :-

∠A and ∠B are complementary angles .

∠A = 71°

Sum of two angles that are complementary to each other will always be equal to 90° .

Which means :-


\longmapsto71° +∠ B = 90°


\longmapsto \: ∠B = 90 - 71


\color{olive}\longmapsto \: \color{hotpink}∠B = 19°

Therefore , the measure of ∠B = 19° .
