The bearings and distances are: Ch 00 A: 156.74 - AY: 95-01-50 414.075 Y-X: 8-12-10 183.805 Calculate the coordinates of point X using the survey data above. Also, using your bearings and distances of each straight of your road, calculate the coordinates of the end of the road. Then, using the coordinates calculated for X and the end of the road, calculate the bearing and distance for a survey party to set out the end of your road from point X.
