The coordinates of point A are 500.000' N, 2000.000' E. Compute the coordinates of the remaining points.
A simple way is to set up a table with North coordinates and latitudes in one column, East coordinates and departures in another.
(2) Inverse Computation
What are the length ad bearing of the line A to C in the diagram below?

From Equations F-5 and F-6:
Substituting into Equation F-7
and Equation F-8
Because ΔN is North and ΔE is West: N86°58'47.6"W
Line AC: 512.39' at N86°58'48"W
