Ok , the vertical height is missing right, so you can use the phythogaros theorem to get $\displaystyle \sqrt{x^2-t^2}$
So again by similar triangles :
$\displaystyle \frac{r}{h}=\frac{x}{\sqrt{x^2-t^2}}$
$\displaystyle xh=r\sqrt{x^2-t^2}$
$\displaystyle x^2h^2=r^2x^2-r^2t^2$
$\displaystyle x^2(r^2-h^2)=r^2t^2$
can take it from here ?
