Answer 2

Supplementary angles: Two angles, the sum of whose measures is 180°, are called supplementary angles :  

(i) Given : Measures of an angle is 54°

Since the sum of the measures of an angle and its supplement is 180°.

∴ Its supplement = 180° – 54° = 126°

 

(ii) Given : Measures of an angle is 132°

Since the sum of the measures of an angle and its supplement is 180°.

∴ Its supplement = 180° – 132° = 48°

 

(iii) Given : Measures of an angle is 138°

Since the sum of the measures of an angle and its supplement is 180°.

∴ Its supplement = 180° – 138° = 42°

Hence, the supplement of the following angles are 126° , 48°  &  42°.
