Answer: 
Step-by-step explanation:
You can observe in the figure that JK is a tangent and KH is a secant and both intersect at the point K. Then, according to the Intersecting secant-tangent Theorem:

You know that:

Then KE is:



Now you can substitute the value of KE and the value of KH into
and solve for JK. Then the result is:
