Explanation:

Complementary angles are those whose sum is 90.
Given here, is a right angled triangle, where anfle C is 90 deg.
In this, sum of Angles A + C = 90,
since, sum of angles in a right angled triangle = 180, angle C = 90 and
hence sum of A + B = 180 - C = 180 - 90 = 90.
Hence, the pair of cimplementary angles in the given triangle = Angle A + B.
