Answer 2

Answer:

Which of the following pairs are complementary?

a) 55°, 115° - ❌

b) 36°, 54° - ✔

c) 78°, 112° - ❌

d) 88°, 22° - ❌

Step-by-step explanation:

Which of the following pairs are complementary?

a) 55°, 115° - These two are not complementary angles as 115° + 55° = 170° which is not equal to 90°

b) 36°, 54° - These two are complementary angles as 36° + 54° = 90°

c) 78°, 112° - These two angles are not complementary as 78° + 112° = 190° which is not equal to 90°

d) 88°, 22° - These two angles are not complementary as 88° + 22° = 110° which is not equal to 90°
