would use tangent if I had the length of the other leg, but I don't I can't do this!"

Davis kept his calm and responded, "You are just forgetting a very useful theorem."
Is Davis right? Can you calculate the value of x with a useful theorem? If so, do it. Or, is Tess right and this can't be done? Why not?
In other case, explain completely. justifying your answer.
