Question

A reverse curve has two simple curves: CURVE A and CURVE B.

CURVE A has a radius of 460 meters.

CURVE A has a central angle of 82 degrees.

The central angle of CURVE B is 80 percent of the central angle of CURVE A.

The external distance of CURVE B is equal to the middle ordinate of CURVE A.
