Answer 1

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

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* x = 8^2`

`4x = 64`

`x=√(16)`

`x=4` cm

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