The symmetrical parabolic curve connecting the tangents passes thru a point at sta. 20+130 with an elevation of 117.525 m. If the highest point on the curve is located 84 m from PT, what is the length of the curve connecting the tangents? Determine also the grade of the descending tangent and the elevation of the highest point on the curve.
