A new landowner has a triangular piece of flat land she wishes to fence. Starting at the west corner, she measures the first side to be 80 m long and the next to be 105 m -- these sides are represented as displacement vectors A and B in Figure 3.26, where ?1=20

A new landowner has a triangular piece of flat land she wishes to fence. Starting at the west corner, she measures the first side to be 80 m long and the next to be 105 m -- these sides are represented as displacement vectors A and B in Figure 3.26, where ?1=20degree, and ?2=10degree. She then correctly calculates the length and orientation of the third side C. What is her result?

Explanation / Answer

x = 105 * cos 58, y = 105 * sin 58 ? 89.045051 m
Total x = 80
