Answer»

i) 150°

ii) 101°

iii) 1°

iv) 144°

Step-by-step EXPLANATION:

supplementary angles are the angles ADDED UPTO 180°.

i) supplementary of 30°= 180° - 30°

= 150°

ii) supplementary of 79°= 180° - 79°

= 101°

iii) supplementary of 179° = 180° - 179°

= 1°.

iv)

$x \: degree \: = \frac{2}{5} right \: angle$

$\: \: \: \: \: \: \: = \frac{2}{5} \times 90$

$\: \: \: \: \: \: = 2 \times 18 = 36$

x° = 36°.

supplementary of 36° = 180° - 36°

= 144°.
