## Homework Statement

solve for x:

[ x / sqrt(x^2 + h^2) ] = [ d / sqrt(d^2 + h^2) ]

I need to solve for x.

## Homework Equations

sq rt * sq rt = what is inside the square root

square both sides of an equation

## The Attempt at a Solution

Can anyone help me remember how to get rid of the sqrt of x on the bottom of the left hand side? If I multiply by the sq rt of the ( ) I will have to do it on the other side, so I will still have the sq rt.

If I square both sides of the equation, I think that I would get: x^2 / (x^2 + h^2) = d^2 / (d^2 + h^2) Is that right? If so, I don't know where to go from there to solve for x?
