WebLaw of Sines: Given Two Angles And One Side. We will first consider the situation when we are given 2 angles and one side of a triangle. Example: Solve triangle PQR in which ∠P = 63.5° and ∠Q = 51.2° and r = 6.3 cm. Solution: First, calculate the third angle. ∠ R = 180° – 63.5° – 51.2° = 65.3°. Next, calculate the sides.
