Grades of g$\_(1)=-2\mathrm{.}50\%$ and g$\_(2)=+1\mathrm{.}50\%,$ VPI elevation $862\mathrm{.}00$ft at station $22+00,$ and a fixed elevation $866\mathrm{.}00$ft at station $20+50.$ Part A Field conditions require a highway curve to pass through a fixed point. Compute a suitable equal$-$tangent vertical curve and full$-$station elevations. Give the elevations in order of increasing x $.$ Express your answers in feet to five significant figures separated by commas. Elev $=$ ft
