Question

Find the value of x!!!!!!!!!!!!

Answer 1

`x=3√(7)`

Explanation:

If a tangent and a secant connect to an exterior point of a circle, the tangent squared is equal to the product of the two segments the secant creates.

Therefore, we have:

`x^2=7 \cdot 9,\\x^2=63,\\x=√(63)=\boxed{3√(7)}`
