Two tangent $PQ$ and $PR$ are drawn from external point $P$ to a circle with center $O$; where $Q, R$ are not the point of tangency. $Q, R$ are two points such that $PQ=PR$ and $O$ is the midpoint of the line $QR$. $X, Y$ are two points situated on $PQ$ and $PR$ respectively in such a way so that $XY$ is a tangent to the circle. If $QR=10$. Then find the value of $QX \times RY$ = ?
