1. Haasbroek (1968, p 88) gives a version of Snel's original angle measurements for mapping the Netherlands, together with an accompanying figure showing the angle labels. The angle data can be given 3-point form (a, b, c) where a, b, c are symbols for the citing locations, with b the center of the angle, e always counter-clockwise of a. Note that all angles are measured by inner are so each is less than 180 degrees. Using these data, and assuming the distance from Breda (B) to Bergen op Zoom (Bz) is 1 mile, how many miles is it from Utrecht (U) to Bergen op Zoom.
