Question

1. Find the complement of:
a. 40°. b. 85°​

Answer 1

Answer:

a:90-40=50

b:90-85=5.

Answer 2

a. 40°

let the require angle be x then,

40° + x = 90° [Sum of complement angles are equal to 90°]

⇒ x = 90° - 40°

⇒ x = 50°

b. 85°

let the require angle be x then,

85° + x = 90° [Sum of complement angles are equal to 90°]

⇒ x = 90° - 85°

⇒ x = 5°
