Question

How do I solve this?(tangent segment)

Answer 1

x = 6

Explanation:

Given a tangent and a secant from an external point to the circle, then

The square of the tangent is equal to the product of the measures of the external part and the entire secant, that is

x² = 4(4 + 5) = 4 × 9 = 36 ( take the square root of both sides )

x =
`√(36)` = 6
