Use the Law of Cosines to solve the triangle. (Round your answers to two decimal places.)a= 43, b = 38, c = 74
Question
Solution 1
Sure, here are the steps to solve the triangle using the Law of Cosines:
Step 1: We can start by finding one of the angles. Let's find angle A. The formula for the Law of Cosines is:
cosA = (b² + c² - a²) / 2bc
Substitute the given values:
cosA = (38² + 74² - 43²) / (2 * 38 * 74)
