Answer 1

Answer:

Length of the segment of a secant 'x' is 4 cm.

Step-by-step explanation:

If a secant and a tangent are drawn from a point outside the circle, then the product of the segments of the secant is equal to the square of the length of the tangent.

By this property,

$4\times x = 8^2$

$4x = 64$

$x=\sqrt{16}$

$x=4$ cm

Therefore, length of the segment of a secant 'x' is 4 cm.
