The long chord from PC to the PT of a compound curve has its angles with the tangent
passing through PC and tangent passing through PT are 11 degrees and 19 degrees,
respectively. The offset distance from PT to the tangent line passing through PC is equal to
81m. If the common tangent is parallel to the long chord. Determine the following:
The radius of the first curve.
The radius of the second curve.
Length of the first curve.
Length of the second curve.
If the stationing of PC is 9200, find the stationing of PT.
