Write the complement angle of :(i) 45°(ii) x°(iii) (x – 10)°(iv)

1.	Write the complement angle of :(i) 45°(ii) x°(iii) (x – 10)°(iv) 20° + y°
Answer» (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 + 10° = 100°-x (iv) Complement angle of 20° + y° = 90°- (20°+ y°) = 90° – 20° -y° = 70° - y°

Write the complement angle of :(i) 45°(ii) x°(iii) (x – 10)°(iv) 20° + y°

Answer»

(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 + 10° = 100°-x

(iv) Complement angle of 20° + y°

= 90°- (20°+ y°)

= 90° – 20° -y° = 70° - y°
