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 80.0 m long and the next to be 105 m. These sides are represented as
displacement vectors A from B in Figure 15. She then correctly calculates the length and orientation of the
third side C. What is her result?
Problem 2: 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 72 m long and the next to be 112 m. These sides are
represented as displacement vectors A and B in the figure.
She then correctly calculates the length of the third side C. What is her result (in meters)?

- A pirate has buried his treasure on an island with five trees located at the points (30.0 m, 20.0 m), (60.0 m, 80.0 m), (10.0 m, 10.0 m), (40.0 m, 30.0 m), and (70.0 m, 60.0 m), all measured relative to some origin, as shown in Figure P1.69. His ships log instructs you to start at tree A and move toward tree B, but to cover only one-half the distance between A and B. Then move toward tree C, covering one-third the distance between your current location and C. Next move toward tree D, covering one-fourth the distance between where you are and D. Finally move toward tree E, covering one-fifth the distance between you and E, stop, and dig. (a) Assume you have correctly determined the order in which the pirate labeled the trees as A, B, C, D, and E as shown in the figure. What are the coordinates of the point where his treasure is buried? (b) What If? What if you do not really know the way the pirate labeled the trees? What would happen to the answer if you rearranged the order of the trees, for instance, to B (30 m, 20 m), A (60 m, 80 m), E (10 m, 10 m), C (40 m, 30 m), and D (70 m, 60 m)? State reasoning to show that the answer does not depend on the order in which the trees are labeled.
