    Answer:

      16.43 meters

    Step-by-step explanation:

    If the shape of the rise is a triangle, then the center of it is half the total length from the end. We can find the rise (y) using the Pythagorean theorem:

      1500.09² = 1500² +y² . . . . .dimensions in meters

      270.0081 = y²

      y = √270.0081 ≈ 16.43 . . . . meters

    About the most it would rise is 16.43 meters.

    ___

    If the shape is an arc of a circle, the height is about 14.2 meters.
