C) $\angle C = {20}^{\circ}$

#### Explanation:

Let $\angle C = x$

According to angle sum property, sum of all interior angles of a triangle = ${180}^{\circ}$

$\therefore x + {73}^{\circ} + {87}^{\circ} = {180}^{\circ}$

$\implies x = {180}^{\circ} - {73}^{\circ} - {87}^{\circ}$

$\implies x = {20}^{\circ}$

$\therefore \angle C = {20}^{\circ}$
