(a) 63°, 117°
(b) 23°, 67° (c) 105°, 75°
(d) 120°, 60° (e) 90°, 90°
(F) 60°, 30°
​

Answer 1

Answer:

Complementary angles are : b, e, and f

Supplementary angles are : a, c, and d

Step-by-step explanation:

Complementary angle : sum of the angles = 90°

Supplementary angle : sum of angles = 180°

Answer 2

Answer:

complementary-(b), (f)

& supplementary - (a), (c), (d), (e)

Step-by-step explanation:

complementary angles are those which make a sum of 90°.

while supplementary angles are those which make a sum of 180°.
