If A, B, and C are the measures of the angles of any triangle and if a, b, and c are the lengths of the sides opposite the corresponding angles, then the Law of Cosines states that a = + c + 2bc cos A. a=b?+c? + 2bc cos A. b2=a?.c? - 2accos . b2 =a? - + 2ac cos B. b2 =a2 -? - 2ac cos B.

If A, B, and Care the measures of the angles of any triangle and if a, b, and c are the lengths of the sides opposite the corresponding angles, then the Law of Cosines states that a = + c + 2bc cos A. a? = b? +c? + 2bc co A. b² = a? + c² - 2ac cos B. b2 = a? -c + 2ac cos B. b2 = a? - c2 - 2ac cos B.
