Refer to the figure: In right triangle $ABC$ with right angle at $C$, the base $AC$ is divided into segments of lengths 7 and 5 by a perpendicular from $B$ to $AC$. This perpendicular creates two right triangles: the left triangle has hypotenuse $x$ and vertical leg $y$, and the right triangle has horizontal leg 5 and vertical leg $y$. The area of triangle $ABC$ is at least 48 but no more than 60. If $y$ is an integer, what is one possible value of $x$?
