WebTo use ONLY the law of cosines you needthree of the four parts. The four parts are three sides and one angle. So you either need 2 sides and an angle to solve for the remaining side or all three sides to solve for an angle. So if you know two angles (which lets you figure out the third so technically three angles) and a side you can't just use ... WebThe Law of Sines. The Law of Sines (or Sine Rule) is very useful for solving triangles: a sin A = b sin B = c sin C. It works for any triangle: a, b and c are sides. A, B and C are angles. (Side a faces angle A, side b faces angle B and. side c faces angle C).
