If a secant segment and tangent segment are drawn to a circle from the same external point, the product of the length of the secant segment and its external part equals the square of the length of the tangent segment.

Therefore,

$\\ AB^2=AD\times AC\\ \\ AB^2=10\times25.6\\ \\ AB^2=256\\ \\ AB=\sqrt{256}\\ \\ AB=16\hspace{5}cm \\$
