(i) Given angle is 54°
Since the sum of an angle and its supplement is 180°
Therefore, its compliment will be:
180° – 54° = 126°
(ii) Given angle is 132°
Since the sum of an angle and its supplement is 180°
Therefore, its compliment will be:
180° – 132° = 48°
(iii) Given angle is 138°
Since the sum of an angle and its supplement is 180°
Therefore, its compliment will be:
180° – 138° = 42°
