Answer:

6.5 cm

Explanation:

Here, the tangent line squared is equal to the secant line times the secant line outside the circle.

That is 20.2² = 14.7 * (14.7 + 2x) --> it is 2x because the secant goes through the whole circle.

Simplify: 408.04 = 216.09 + 29.4x

Subtract: 191.95 = 29.4x

Divide: x = 6.528911565 ≈ 6.5 cm
