Please show me the solution to this

1. The long chord of a compound is equal to 250 m. The PC this curve is at STA 10+000 and P.C.C. is at 10+139.393. The angle
that the chord connecting the P.C. and P.C.C. makes with the tangent passing through P.C. is equal to 40. Assuming that the
common tangent is parallel to the long chord.
a. Compute R1 ans. 998.329m
b. Compute R2 ans. 639.516m
c. Determine the station of P.I. of the compound curve. ans 10+140.484
