Solving for angles using law of cosines

WebTheorem 3.3 (The Law of Cosines for Angles): Given a spherical triangle with two angles A and B and the side γ between them, we can compute the cosine of opposite angle, Γ, with Proof: Consider 4A0B0Γ0, the dual of 4ABΓ, with sides α0, β0, and γ0. Apply The Spherical Law of Cosines to compute γ0: 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.
