The long chord of a compound curve is equal to 250 meters. The PC this curve is at STA 10+000 and the P.C.C. 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°. Assuming that the common tangent is parallel to the long chord. a. Compute the radius R1 b. Compute the radius R2 c. Compute the stationing of the P.I. of the compound curve
