If the angle you are solving for might be the largest angle, it is less confusing to use the Law of Cosines than it is to use the Law of Sines to solve for it. Example 5: We have a triangle with sides of 132 ft, 73 ft, and 92 ft. Find the size of the largest angle. (Report the angle to three decimal places.) Solution: Use the Law of Cosines.
