WebSo the law of cosines tells us that 20-squared is equal to A-squared, so that's 50 squared, plus B-squared, plus 60 squared, minus two times A B. So minus two times 50, times 60, times 60, times the cosine of theta. This … WebThe Law of Cosines relates the sides & angles of a triangle, using the cosine function. If the triangle’s sides are a, b, & c, with side c across from angle C, then the Law of Cosines says that a2 + b2 – 2abcos (C) = c2. We can use this equation to solve for an unknown side or angle in a triangle. Of course, there are some situations where ...
