Want to learn more about the law of cosines? Check out this video. Practice set 1: Solving triangles using the law of sines This law is useful for finding a missing angle when given an angle and two sides, or for finding a missing side when given two angles and one side. Example 1: Finding a missing side Let's find A C in the following triangle: 1. You can find C. (hint: sum of all angles in a triangle = 180) 2. Set up the ratio using the side given and one of the other angles. ______ = _______ and solve for the missing side. 3. You can repeat this if you need to know all of the sides. Case 2: given SAA B = 10o, C = 100o, c = 115 You have enough information to set up a ratio.

The Law of Cosines is another trigonometric law that relates the lengths of the sides of a triangle to the cosine of one of its angles. For any triangle with sides of length a, b, and c, and opposite angles A, B, and C, the Law of Cosines is expressed as follows: c 2 = a 2 + b 2 - 2ab cos (C) The law of cosines is a formula that relates the three sides of a triangle to the cosine of the included angle. Gain a comprehensive understanding on the cosine law by downloading our rich resources on a variety of topics like finding the missing side, finding the unknown angle, solving each triangle and many more.
