Select the angle that correctly completes the law of cosines for this triangle.52 + 132 – 2(5)(13)cos ___ = 122A.90°B.23°C.67°D.180°
Question
Solution 1
The Law of Cosines is used to find the third side of a triangle when we know two sides and the angle between them. The formula is c² = a² + b² - 2abcosC, where C is the angle between sides a and b.
In this case, we have a = 5, b = 13, and c = 12. We are looking for the angle C that makes this equat Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
