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. WebWe can use the following equation to represent the triangle: x^\circ + 42^\circ + 106^\circ = 180^\circ x∘ + 42∘ + 106∘ = 180∘. The missing angle is 180^\circ 180∘ minus the measures of the other two angles: x^\circ = …
