Law of cosines for angles
WebLaw of Cosines A simple program that will allow a user to find an unknown side of a triangle or an unknown angle of a triangle using the Law of Cosines. lawcosin.zip: 1k: 04-04-06: Law of Cosines The Law of Cosines for determining sides or angles of a triangle when given three sides or two sides and the inner angle. lawcos.zip: 1k: 99-12-20 ... WebThe law of cosines relates the three sides of the triangle to one of the angles. You can use it in a couple of ways. First, if you know one angle and the two adjacent sides, then you can determine the opposite side. For instance, if angle C = 60°, side a = 5, and side b = 8, then the law of cosines says c2 = 25 + 64 – 80 cos 60°.
