Question

Which of the following pairs of angles is not a pair of supplementary angles? a. 90°, 90° b. 32°, 58° c. 76°, 104°​

Answer 1

Step-by-step explanation:

Given : pair of angles  a. 90°, 90° b. 32°, 58° (c) 0°, 180° d. 76°, 104°

To Find : Which of the following pairs of angles is not a pair of supplementary angles

Solution:

Two angles are called supplementary when their measures add up to 180 degrees.

a) 90°, 90°

=> 90° + 90° = 180°

pair of  supplementary   angles

b) 32°, 58°

=> 32°+ 58° =  90°

90°  ≠ 180°

Hence not a pair of supplementary angles

(c) 0°, 180°

=> 0° +  180° = 180°

pair of  supplementary   angles

d)  76°, 104°

=> 76° +  104° = 180°

pair of  supplementary   angles

Hence b. 32°, 58°  is not a pair of supplementary angles
