17. Find the length of the required tangent

\(TP\) and \(TQ\) are two tangents from the point \(T\) to the circle having its centre at \(O\). \(AB\) is another tangent touching the circle externally at \(E\) intersecting \(TP\) at \(A\) and \(TO\) at \(Q\). If the radius of the circle is 9 \(cm\) and the length of \(OT\) passing through \(E\) is 41 \(cm\), calculate the length of \(AB\).
