We can use the Pythagorean theorem to solve for x. Since JK is tangent to JL, we know that JL is perpendicular to JK. Thus, we can treat JL as the height of the right triangle formed by JK and LK.
Using the Pythagorean theorem:
JK^2 + JL^2 = LK^2
x^2 + 11^2 = 7^2
x^2 + 121 = 49
x^2 = 49 - 121
x^2 = -72
Since x is a length, it cannot be negative. Thus, there is no real solution for x.
Therefore, the answer is none of the above.
