Figure length of triangle sides

Web1. The angles always add to 180°: A + B + C = 180°. When you know two angles you can find the third. 2. Law of Sines (the Sine Rule): a sin (A) = b sin (B) = c sin (C) When there is an angle opposite a side, this equation comes to the rescue. Note: angle A is opposite side a, B is opposite b, and C is opposite c. WebMar 26, 2016 · Solve for the missing side. You divide by sin 68 degrees, so. Repeat Steps 3 and 4 to solve for the other missing side. Setting b and c equal to each other, you have this equation: Cross multiply: Divide by sin 68 degrees to isolate the variable and solve: State all the parts of the triangle as your final answer.
