(b) 49°
(c) 139
(d) 149
(а) 590​

Answer 1

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°
