Question

If a°and 70° are a pair of complementary angle, then a° =​

Answer 1

Answer:

Two angles are called complementary angles, if their sum is one right angle i.e. 90°. Each angle is called the complement of the other. Example, 20° and 70° are complementary angles, because 20° + 70° = 90°. Clearly, 20° is the complement of 70° and 70° is the complement of 20°.
