Question

$\text{Mesure of an angle given below. Find the measure of its supplementary angles}$

$\frac{3}{5}thofarightangletriangle$

Answer 1

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

Measure of one supplementary angle $=\frac{3}{5}\times {90}^o={54}^o$

$\Rightarrow$ Measure of another supplementary angle $={180}^o-{54}^o$

$={126}^o.$

$\therefore$ Measure of a supplementary angle of ${54}^o={126}^o$
