from the mirror, as shown in the figure. Her eyes are

    This is similar triangles

    h/6 = 33/9.7

    Multiply both sides by 6

    h = 33/9.7 * 6

    h = 20.412371134

    20 Feet <–––––

    This is a simple geometry problem. It's a right triangle. The hypoteneuse equals the square of the sum of the squares of the other two sides.
