Answer 2

Question -:

Identify which of the following pairs of angles are complementary or supplementary?

a) 160°, 30°

b) 45°, 45°

c) 30°, 60°

d) 135°, 45°

e) 10°, 170°

Explanation -:

We know that if the sum of two angles is 180 degrees then they are called supplementary angles, whereas if the sum of two angles is 90 degrees, then they are called complementary angles.

a) 160°, 30°

→ 160° + 30° = 190°

They are neither complementary angles nor supplementary angles.

b) 45°, 45°

→ 45° + 45° = 90°

They are complementary angles.

c) 30°, 60°

→ 30° + 60° = 90°

They are complementary angles.

d) 135°, 45°

→ 135° + 45° = 180°

They are supplementary angles.

e) 10°, 170°

→ 10° + 170° = 180°

They are supplementary angles.
