Law of Sines & Cosines (worksheets, printable, online, answers)
Law of Cosines. The Law of Cosines is another trigonometric law that relates the lengths of the sides of a triangle to the cosine of one of its angles. For any triangle with sides of length a, b, and c, and opposite angles A, B, and C, the Law of Cosines is expressed as follows: c 2 = a 2 + b 2 - 2ab cos (C)
