Question

Points A and B are in the overlap area between the north and the south zones of Washington State Plane Coordinate System. Point C is in the south zone and is outside of the overlap area. In a survey that extended from the north zone to the south zone, the coordinates of points A and B in the north zone are:

- XA = 774,420.21 m, Y = 96,745.21 m,
- XB = 471,458.25 m, YB = 46,854.68 m
Coordinates of point C in the south zone are:
Xc=499,608.54m, Yc = 55,608.3 m
Use WOLFPACK to compute the grid azimuth of the line BC in the south zone and calculate by hand the length of the line AC. Note that all coordinates are in meters and the reference ellipsoid is GRS80.

Answer 1

To find the grid azimuth of line BC in the south zone and the length of line AC, use WOLFPACK for the grid azimuth and the distance formula for the length of line AC.

Step-by-step explanation:

The student is asking for the grid azimuth of the line BC in the south zone and the length of the line AC. To find the grid azimuth, you can use the WOLFPACK tool. To calculate the length of line AC, you can use the distance formula. Here are the step-by-step instructions:

1. Use WOLFPACK to compute the grid azimuth of the line BC in the south zone.
2. To calculate the length of line AC, use the distance formula:
   AC = √((XC - XA)^2 + (YC - YA)^2)
