A man start from a point A and walks a distance of 3.0km due Northeast to point B. From point B he then walk 4.0 km due Southeast to point X.
Calculate the shortest distance between A and X.

A man runs 500m at 37° North by east then runs another 1000m at 60°west by north. Determine the module of the run and the orientation.
