A $-2\mathrm{.}5\%$ grade meets a $+2\mathrm{.}50\%$ grade at station $4+200$ and elevation

$154\mathrm{.}657m,180-m$ curve, stakeout at $30-m$ increments.

Part A

List station elevations, including $BVC$ and EVC, for an equal$-$tangent parabolic curve for the data given. Give the elevations in order of increasing $x.$

Express your answers in meters to six significant figures separated by commas.
