A new landowner has a triangular piece of at land she wishes to fence. Starting at the west corner, she measures the rst side A to be 63,1 m long and the next side B to be 118,1 m. These sides are represented as displacement vectors A and B in the gure below. The angle between A and the x7 axis is 13,1 degrees, and the angle between B and the yaxis is 12,3 degrees. She then correctly calculates the length and orientahon of the third side C. What is the magnitude of the vector C in meters
