WebLaw of Sines and Cosines Examples - Examples Question 1 : In a triangle ABC, if cos C = sin A / 2 sin B, show that the triangle is isosceles. Solution : cos C = sin A / 2 sin B cos C (2 sin B) = sin A 2 sin B cos C = sin A sin (B + C) + sin (B - C) = sin A A + B + C = 180 B + C = 180 - A sin (180 - A) + sin (B - C) = sin A WebSine Law And Cosine Law Worksheets.Let us have an example while learning factorization.
