Answer:

D

Step-by-step explanation:

The line x originates from the center of the circle and forms a perpendicular line with line RS, which means that the line is bisected.

That means that line RT is half of line RS, or 7.

Then we can use the Pythagorean Theorem to find the measure of x.

[tex]7^2+b^2=9^2[/tex]

[tex]49+b^2=81[/tex]

[tex]b^2=32[/tex]

b = √32

b ≈ 5.66
