Answer:

a)

Your explanation:

I am Ace (36 Brainliest)

I am sure with my answer.

For 'a'

If we take 2 acute angles (0° > 90°), 40° and 50°

A pair of angles is said to be complementary when their sum is 90°.

To check 'a',

40° + 50° = 90°

90° = 90°

A pair of acute angles can be complementary.

For 'b'

If we take 2 obtuse angles (90° > 180°), 100° and 115°

A pair of angles is said to be complementary when their sum is 90°.

To check 'b',

100° + 115° = 215°

215° ≠ 90°

A pair of obtuse angles can never be complementary.

For 'c'

If we take 2 right angles (90°)

A pair of angles is said to be complementary when their sum is 90°.

To check 'c',

90° + 90° = 180°

180° ≠ 90°

A pair of right angles can never be complementary.

For 'd'

If we take a obtuse and a acute angle (91 and 1)

A pair of angles is said to be complementary when their sum is 90°.

To check 'd',

91° + 1° = 92°

92° ≠ 90°

A pair of a obtuse and a acute angle can never be complementary.
