\(PQR\) is an isosceles triangle where \(PQ = PR\). \(X\) is a point on the circumcircle of \(\triangle PQR\), such that it being in the opposite region of \(P \) with respect to \(QR\). The normal drawn from the point \(P \) on \(XR\) intersects \(XR\) at point \(Y\). If \(XY = 10 \), then find the value of \(QX + RX\).
