WebApr 11, 2024 · 1. If ∠B = 21°, ∠c = 46 and side AB = 9 cm in a triangle then solve the triangle. Solution: Given: Two angles and a side. No, let’s use law of sine to solve the triangle. As we know sum of the interior sides of a triangle is 180° Accordingly, ∠A = 113° As AB = c= 9cm. Using the law of sine rule: 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.
