NEED HELP SOLVING THIS....,....$\mathrm{.}1-$ For a circular highway curve to the right with radius of $775ft,I=38{30}^{\text{'}}{35}^{\text{'}\text{'}},$ and $\frac{?}{PI}=63+50\mathrm{.}50$ feet,

a$)$ Find Degree of curvature, Length of the curve, Tangent, External ordinate, Middle ordinate, Long chord, and stations of the PC and PT$.$ Use the arc definition for degree of curvature.

b$)$ Tabulate the curve data, deflection angles, and incremental chords needed to lay out a circular highway curve at PC$,$ full$-$station increments and PT$.($Do not forget to tabulate your results$).$
