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**
