Given a simple circular curve with the following properties: D = 11°, bearing on incoming (back) tangent is N 89°27’25’’ E, bearing on outgoing (forward) tangent is S 60°10’05’’ E, the station of the PI = 22 + 69.77.

Determine:

• The intersection angle (Δ)
• The radius (R)
• The tangent (T)
• The external distance (E)
• The middle ordinate (m)
• The long chord (C)
• The length of the curve (L)
• Station of the PC
• Station of the pT
