    The theorem I think we need is this one: Theorem: If an altitude is drawn to the hypotenuse of a right triangle, either leg of the triangle is the geometric mean between the length of the hypotenuse and the segment of the hypotenuse adjacent to that leg.

    @sharon_penn I'm waiting for you to say something about solving the equations on the attachment.

    I know how to do this and will help if you will just tell me what your thinking is on the problem.

    My thought was that the sides would equal so I thought that the answer x=2sqrt3 y=4 was correct

    I'll work the equation here. y/12 = 28/y y = 4*sqrt(21)

    16/x = x/28 x = 8*sqrt(7)
