For completeness , I prove that the area equals $frac{1}{2}absin c$
.Let the sides of known measures be $AB$ and $AC$ . Let the known angle be $angle BAC$
Draw perpendicular $CD$ to $AB$ . Then , the area = $$frac{1}{2}bh=frac{1}{2}ABcdot CD=frac{1}{2}ABcdot (ACcdot sin angle CAB) $$

Nice answer, certainly not a lazy one like mine. cdot $( cdot ) $ might help your formatting, though you can choose to ignore this.
