The proposed highway has two tangents of bearings N 45Degrees 54' 36" E and N 1 Degree 22' 30" W. The highway design engineer, attempting to obtain the best fit for the simple circular curve join these tangents, decides that the external is to be 43 ft. The PI is at station 65+43.21. Determine : a) The central angle of the curve, b) The radius of the curve, c) The length of the tangent of the curve, d) The Station of the PC, e) The length of the curve, f) The station of the PT, g) The deflection angle and chord from the PC to the first full station on the curve.
