WebExample 2: The lengths of the two sides of a triangle ABC are 10 units and 9 units and the angle between them is 47°. Find the length of the third side of the triangle. Solution: To find the length of the third side of the triangle, we will use the law of cosines. We have a = 10, b = 9, and angle C = 47°. We need to find the value of c. So ... WebThe suggestion is to use the Cosine Law to determine the angle opposite a largest side. Then we will know that the other angles are acute, so Sine Law goes smoothly. This works for all triangle types. $\endgroup$
