Question

Measures of some angles are given below. Find the measures of their supplementary angles.

108${}^o$

Answer 1

Supplementary angles are two angles with a sum of ${180}^o.$

One supplement angle is ${108}^o.$

$\Rightarrow$ Other supplement angle $={180}^o-{108}^o$

$={72}^o.$

$\therefore$ Measure of a supplementary angle of ${108}^o={72}^o$
