To find the value of \( x \), let's analyze the given diagram and relationships carefully. Here, we'll focus on solving for \( x \) using the geometric properties of the tangents and the circle.

Given:
- \( \overline{OL} \) is the radius of the circle, which is 16.
- \( \overline{MN} \) is tangent to the circle.

We need to consider the lengths provided:
- \( \overline{ML} = x - 3 \)
- \( \overline{LN} = x + 3 \)

First, note that the length of the tangent segments from a common external point to a circle is equal. Therefore, we use the Pythagorean theorem on \( \triangle OLN \) and \( \triangle OLM \) respectively:

For \( \triangle OLN \):
\[
\overline{ON}^2 = \overline{OL}^2 + \overline{LN}^2
\]
\[
ON^2 = 16^2 + (x + 3)^2
\]

For \( \triangle OLM \):
\[
OM^2 = \overline{OL}^2 + \overline{ML}^2
\]
\[
OM^2 = 16^2 + (x - 3)^2
\]

Now, since \( ON \) and \( OM \) are radii of the circle:
\[
ON = OM = 16
\]

Therefore:
\[
16^2 = 16^2 + (x + 3)^2
\]
This doesn't necessarily help alone.

For lengths generally the triangles in perspective to find segment tangent, effectively relate:
\[
\overline{MN} = \sqrt{(x-3)^2 + (x+3)^2}
\]

Solving for \( MN \):
\[
\overline{MN} = \sqrt{2x^2 + 2 \cdot 3^2}
\]
\[
\overline{MN} = \sqrt{2x^2 + 18}
\]

For actual general radius tangent property:
\[
(x^2 - 16^2) = (x^2 + 9 - 256)
\]

Thus effectively simpler for line radius:
Solving:
\[
 x = 3 + 4 = 4(3) MN\]
With proper distance checked.

Thus from proper line perspective:
Directly tangent validate:
