Question 1

Q1)

Write the complement angle of :

(i) 45°

(ii) x°

(iii) (x – 10)°

(iv) 20° + y°

Solution:

(i) Complement angle of 45°

= 90° - 45° = 45°

(ii) Complement angle of x°

= 90° - x° = (90 - x)°

(iii) Complement angle of (x -10)° = 90(x-10)°

= 90° - x° = (90 - x)°

(iv) Complement angle of 20° + y°

= 90°- (20° + y°)

= 90° - 20° - y° = 70° - y°
