Curve setting

A curve is a turn that is provided horizontally or vertically in the design of highways, railways, and runways. A curve connects two straight lines that are separated by the deflection angle. It helps to change the direction and alignment of the highways, railway tracks, and runways. Therefore, the gradual change in their alignment is made by using a curve to provide comfort to the passengers and this also provides an easy turn to change the direction of the moving vehicle.

Question

A compound curve is to connect two straights having a deflection angle of 90 degree. Length of two
tangents are 350 meters and 400 meters respectively. Calculate the lengths of two arcs if the radius
of the first curve is to be 300 meters.
