      The Law of Sines works just as well if the side c is given instead of the angle C. In that case, we solve for sin(C) and then use the inverse-sine function to calculate the angle C. Example 2: Find the size of angle A in the illustrated triangle: C=79(, a=36 mm, and c=50. mm. Considering significant digits, the final answer is A = 45
