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.

WebIf we know the length of any two sides and perimeter of the triangle, then we can easily find the length of the third side. Example: The perimeter of a triangle ABC is 150 cms and the length of the two sides AB and BC is 50cm and 60 cms, respectively. Then, find the length of the third side. Solution: Given, perimeter = 150 cms. AB = 50cm. BC ... WebDec 21, 2024 · Add the two known angles together and subtract the total from 180. All angles inside a triangle must add up to 180 degrees.
