Answer:
B
Step-by-step explanation:
Since the line segment JK is tangent to the circle C, it creates a 90° angle at the point of intersection.
This means that we can use the Pythagorean Theorem.
[tex]a^2+b^2=c^2[/tex]
Plug in the values given.
[tex]24^2+b^2=28^2 \\ \\ 576+b^2=784 \\ \\ b^2=208 \\ \\ b=\sqrt{208} \\ \\ b=14.4[/tex]
