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 the figure below, where e, = 21°, and 8, = 10°. A + B +C = 0 e = ? C = ? m B = 105 m Be, E A = 80 m She then correctly calculates the length and orientation of the third side C. What is her result in meters and degrees south of west? 74 m 52.85 O south of west

Question
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
and B in the figure below, where e, = 21°, and e, = 10°.
A + B + C = 0
e = ?
C = ? m
B = 105 m
Be,
