Horizontal Curves $($EC$-2)$

A highway curve is designed to connect two tangents that intersect at PI STA $29+64\mathrm{.}20.$ The radius of the curve is $1,521\mathrm{.}12$ feet. The deflection angle between the two tangents is $16{30}^{\text{'}}{00}^{\text{'}\text{'}}.$ Compute the following properties of the highway curve: degree of curvature in DMS$,$ the length of the curve in feet, the tangent distance, the long chord distance, the middle ordinate, the external distance. Compute the PC STA and the PT STA for the highway curve. All distances and stationing will be to the hundredths of a foot.

This extra credit opportunity is worth twenty points.
