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. Find the: - tangent distance of CURVE B - Length of long chord of CURVE B - angle of intersection of the reverse curve
