Question

1 If m and 65° are a pair of complementary angles,find x.
2 If y and 102° are a pair of supplementary angles,find a.

Answer 1

Answer:

required answer -

∠PQR and ∠QRP are complementary as ∠PQR + ∠QRP = 40° + 50° = 90°. Angles of measure 25° and 65° are complementary angles. The angle of 25° is the complement of the angle of 65° and the angle of 65° is the complement of the angle of 25°.
