The long chord of a compound curve is equal to 250 meters. The PC of this curve is at Sta 10+000 and the PCC is at 10+139.393. The angle that the chord connecting the PC and PCC makes with the tangent passing through PC is equal to 4 degrees. Assuming that the common tangent is parallel to the long chord, Evaluate the Radius R1 and R2
