(i) Given angle is 20°
Since the sum of an angle and its compliment is 90°
Therefore, its compliment will be:
90° – 20° = 70°
(ii) Given angle is 35°
Since the sum of an angle and its compliment is 90°
Therefore, its compliment will be:
90° – 35° = 55°
(iii) Given angle is 90°
Since the sum of an angle and its compliment is 90°
Therefore, its compliment will be:
90° – 90° = 0°
(iv) Given angle is 77°
Since the sum of an angle and its compliment is 90
Therefore, its compliment will be:
90° – 77° = 13°
(v) Given angle is 30°
Since the sum of an angle and its compliment is 90°
Therefore, its compliment will be:
90° – 30° = 60°
