Twenty degrees north-by-northeast with respect to what? The position of louisville kentucky? the problem with thinking of north changing is that, east is a direction on a flat plane, so are taking this with respect to a flattened line of longitude? How do we get back from the now, more east, postion w.r.t. the line of longitude and get back to the curved plane?
Am i misunderstanding this?
