Answer:

y = 11.2 in.

Step-by-step explanation:

To solve this question we will use the theorem of intersecting secants and tangents.

"If a secant and a tangent are drawn to a circle from an external point then length of tangent is the geometric mean between the length of external segment of the secant and the length of the secant."

By this theorem,

5(5 + y) = (9)²

y + 5 = [tex]\frac{81}{5}[/tex]

y = 16.2 - 5

y = 11.2 in

Therefore, y = 11.2 in. will be the answer.
