Question

identify the complementary angles and which are not from the following pairs​

Answer 1

Answer:

b) (45°, 45°) and d) (37°, 53°) are complementary pairs

a)  (80°, 20°) and c) (50°, 30°) are not complementary pairs

Step-by-step explanation:

Complementary angles add up to 90°

a) 80° + 20° = 100° ≠ 90°  ∴ This is not a complementary pair.

b) 45° + 45° = 90°   ∴ This is a complementary pair.

c) 50° + 30° = 80° ≠ 90°  ∴ This is not a complementary pair.

d) 37° + 53° = 90°   ∴ This is a complementary pair.
