Question:medium
In the adjacent figure \(PT\) is a tangent drawn from an external point \(P\) touching the circle at \(T\). \(PAB\) is a secant cutting the circle at \(A\) and \(B\). If \(PT=5\) cm and \(PA=4\) cm, then \(AB\) (in cm) is
In the adjacent figure \(PT\) is a tangent drawn from an external point \(P\) touching the circle at \(T\). \(PAB\) is a secant cutting the circle at \(A\) and \(B\). If \(PT=5\) cm and \(PA=4\) cm, then \(AB\) (in cm) is
Show Hint
For tangent and secant from the same external point, always use \(PT^2=PA\cdot PB\).
