Triangles calculations
WebJun 26, 2013 · 3. For the first one, use the fact that the sum of the interior angles of a triangle is 180 o to find the 3 rd angle and then use the sine law. The third angle is 180 − 50 − 60 = 70. The sine law states that ratio of the sines of two angles of a triangle is equal to the ratio of their opposite side lengths. We can use it to find b: b 3 ... Websin (A) < a/c, there are two possible triangles. solve for the 2 possible values of the 3rd side b = c*cos (A) ± √ [ a 2 - c 2 sin 2 (A) ] [1] for each set of solutions, use The Law of Cosines to solve for each of the other two angles. present 2 full solutions. Example: sin (A) = a/c, there is one possible triangle.
