WebIf given one angle of a triangle and two sides, it is possible for two triangles to exist given the same dimensions. For example if told to find the missing sides and angles of a triangle given angle A is 19 degrees, side a is length 45, and side b length 44, you may begin by using the law of sines to find angle B. This is shown below: WebAnswer: The length of the third side of the triangle is 7.63 units. Example 3: In triangle ABC, ∠C = 42° and ∠A = 33°, and the side opposite to angle C is 12.5 units. Find the length of the side of the triangle opposite to angle A. Solution: We have ∠C = 42° and ∠A = 33°, c = 12.5 units. We need to find the side 'a'.
