Question

Identify the pair of complementary angle
(a) 85°, 15°
(b) 100°, 80°
(c) 120°, 60°
(d) 65°,35°

Answer 1

Answer:

a) 85 + 15= 100"

Therefore, these angles are not complementary.

b) 100 + 80= 180"

Therefore, these angles are not complementary. It's supplementary.

(If the sum of two angles is equal to 180", then they are supplementary).

c) 120 + 60= 180"

Therefore, these angles are not complementary. It's supplementary.

d) 65 + 35= 100"

Therefore, these angles are not complementary.
