Question

Find the value of x. If necessary, round your answer to the nearest tenth. The figures are not drawn to scale.

The figure consists of a tangent and a secant to the circle.

Answer 1

Answer:

$x=9.4$

Step-by-step explanation:

we know that

Applying the Intersecting Secant-Tangent Theorem

$(18+4)(4)=x^{2}$

$(22)(4)=x^{2}$

$88=x^{2}$

square root both sides

$x=9.4$
