For a highway curve with Da=5∘00′, I=20∘30′, and PI station=63+25.53ft, calculate the requested values to lay out the circular curve at full stations (100 ft). Tabulate stations, deflection angles, and incremental chords to lay out the curve at full stations (100 ft). Express angles in degrees to four decimal places; express first station numbers as integers; second station numbers and chord lengths should be expressed in feet to two decimal places. The PC station should be placed at the bottom of the table. Radius - 1,145.92ft Curve Length = 410 ft Tangent Distant = 207.22 ft Middle Ordinate = 18.29 ft External Distance = 18.58 ft Please show me the steps of what I need to do to fill the chart with the information I already have. See picture for chart.

Question
For a highway curve with Da=5∘00′, I=20∘30′, and PI station=63+25.53ft, calculate the requested values to lay out the circular curve at full stations (100 ft).
Tabulate stations, deflection angles, and incremental chords to lay out the curve at full stations (100 ft).
Express angles in degrees to four decimal places; express first station numbers as integers; second station numbers and chord lengths should be expressed in feet to two decimal places. The PC station should be placed at the bottom of the table.
Radius - 1,145.92ft
Curve Length = 410 ft
Tangent Distant = 207.22 ft
Middle Ordinate = 18.29 ft
External Distance = 18.58 ft
Please show me the steps of what I need to do to fill the chart with the information I already have. See picture for chart.
