Finding Side Length in a Triangle Using Law of Sines

In triangle ABC, angle A measures $60^{ ext{o}}$ and angle B measures $30^{ ext{o}}$. The side opposite angle A (side a) has a length of 12 units. Calculate the length of side c (opposite angle C) using the Law of Sines.

Recall that angle C can be found using the fact that the sum of the angles in a triangle is $180^{ ext{o}}$.
