Question 4

Diagram of a circle with center O. A tangent line AC touches the circle at point A. A secant line OBC passes through the center O and intersects the circle at point B. The radius OA is labeled 8 cm, and the tangent segment AC is labeled 15 cm.

$A\,$ and $B\,$ are points on the circumference of a circle, centre $O$ . $AC\,$ is a tangent to the circle. $OBC\,$ is a straight line.

$8\text{ cm}$ $15\text{ cm}$

Find the length of $B C$ .
