Homework Help: Pythagorean theorem help

  1. Apr 16, 2012 #1
    1. The problem statement, all variables and given/known data
    Find line FC in the given problem.

    2. Relevant equations
    A^2 + b^2 = c^2

    3. The attempt at a solution
    according to the diagram,
    1/2ac = bc - since the the two right triangles share the same hypotenuse.
    bc = 12
    so 1/2ac = 12,
    i got the answer as 16^2 + b^2 = c^2,
    is that correct?

    Is it intended that we regard ABCD as a rectangle? It isn't marked as such.
    But you could construct many different right triangles all having the same length hypotenuse.
    Can you express FC in meters?
