Question

1. The angles x and 90° – x are
(a) supplementary (b) complementary
(c) vertically opposite (d) making a linear pair
2. The angles x – 10° and 190° – x are
(a) interior angles on the same side of the transversal
(b) making a linear pair
(c) complementary
(d) supplementary

Answer 1

Answer:

1. The sum of the two angles x and 90° – x is 90°.

Hence they are complementary

2. The sum of the two angles is 180°.

Hence they are supplementary

Answer 2

Ans: Complementary angle:- sum of two angles is equal 90° .

given angles , x and 90 - x

x + 90 - x = 90

therefore , angle x and 90 - x is Complementary to each other.
