WebApr 7, 2024 · For example, consider A B C with ∠ B = 88 ∘, a = 4.4, c = 5.2 where I got side b = 6.694 by Law of Cosines and then the following angle solutions using different methods: finding ∠ A = 41.064 ∘ using Law of Sines and then finding ∠ C = 50.936 ∘. I also got these solutions by using Law of Cosines to find angle A as a second step. WebThe Law of Cosines states that: c 2 = a 2 + b 2 - 2ab * cos(C) Where c is the length of the side opposite angle C, a and b are the lengths of the other two sides, and C is the measure of the angle opposite side c. You can use this formula to find the measure of each angle by plugging in the known side lengths and solving for the angle.
