An 8° simple curve connecting two tangent that intersect at an angle of 88° is to be replaced by a symmetrical three centered compound curve at the center having 6’ end curves and a 10° curve at the center maintaining the same P.C. Use chord basis.

1. Find the central angle of the 10° center curve.

2. Find the central angle of the 6° end curves.

3. Find the stationing of the P.T. if P.C. is at 10+185.42.
