Question

6. The tangent and a secant to a circle are from the same external point. If the tangent is 6 inches and the external segment of the secant is 3 inches, compute the length of the secant.

Answer 1

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.

b*c=a^2

plugging in

3*c=6^2

Answer 2

Thank you :)
