How To Use The Cosine Rule To Find An Angle Youtube The law of cosines is used in determin learn how to solve for the lengths of the sides and the measures of the angles of a triangle using the law of cosines. Law of cosines calculator. This trigonometry video tutorial provides a basic introduction into the law of cosines. it explains how to use the law of cosines formula for finding angles. We can use the law of sines to solve triangles when we are given two angles and a side (aas or asa) or two sides and a non included angle (ssa). the law of cosines, for any triangle abc is. a 2 = b 2 c 2 – 2bccos a. b 2 = a 2 c 2 – 2ac cos b. c 2 = a 2 b 2 – 2ab cos c. the following diagram shows the law of cosines.
