A) B + C B) A + C
C) C + C D) B + A
 
Answer & Explanation Answer: D) B + A

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.
