WebThe cosine rule, also known as the law of cosines, relates all 3 sides of a triangle with an angle of a triangle. It is most useful for solving for missing information in a triangle. For example, if all three sides of the triangle are known, the cosine rule allows one to find any of the angle measures. Similarly, if two sides and the angle between them is known, the … WebSolution 3. Let . Let the circle intersect at and the diameter including intersect the circle again at . Use power of a point on point C to the circle centered at A. So . Obviously so we have three solution pairs for . By the Triangle Inequality, only yields a possible length of . Therefore, the answer is .
