In a circle, the measure of an inscribed angle is half the measure of the arc that it subtends. Given that \(\angle JMK\) measures \(82^\circ\) and it subtends arc \(JK\), we can set up the following equation:

\[
\frac{1}{2} \text{(measure of arc JK)} = \angle JMK
\]

Substituting the values we have:

\[
\frac{1}{2}(5x - 6) = 82
\]

To eliminate the fraction, multiply both sides by \(2\):

\[
5x - 6 = 164
\]

Next, add \(6\) to both sides:

\[
5x = 170
\]

Now, divide both sides by \(5\):

\[
x = 34
\]

However, this value doesn't seem to match any responses you provided. Let's double-check the options given. It seems I might have miscalculated in my interpretation of the angle and arc relationship.

Considering the relationship between the angle and the arc again:

\[
\text{measure of arc JK} = 5x - 6
\]
\[
\frac{1}{2}(5x - 6) = 82
\]
So, re-confirming:

\[
5x - 6 = 164
\]
\[
5x = 170
\]
\[
x = 34
\]

Since the calculation keeps resulting to \(34\), please verify the provided values or check the entire setup because based on this angle and arc relationship, \(x\) definitely resolves to \(34\).
