WebThe formula for the law of cosines is an equation that relates the lengths of two sides of a triangle to the angle between the two sides. The formula for the law of cosines is: { {a}^2}= { {b}^2}+ { {c}^2}-2bc\cos (\alpha) a2 = b2 + c2 −2bccos(α) { {b}^2}= { {a}^2}+ { {c}^2}-2ac\cos (\beta) b2 = a2 +c2 −2accos(β)
