To solve for \( x \) in this problem, we need additional information and a clear diagram or description. From the given information, we know that line segment \( \overline{ST} \) is the perpendicular bisector of line segment \( \overline{QR} \).

A perpendicular bisector has two key properties:
1. It intersects \( \overline{QR} \) at a 90-degree angle.
2. It divides \( \overline{QR} \) into two equal parts, meaning \( Q \) and \( R \) are equidistant from the point of intersection (let's call this point \( M \)).

Without the coordinates of the points \( Q \), \( R \), \( S \), and \( T \), or an equation to set up, it is not possible to definitively solve for \( x \).

However, if we assume that the task involves setting up a segment length equation using these properties, we can address this with a hypothetical example. Let's assume \( M \) is the midpoint of \( \overline{QR} \), and can express \( QM = MR \).

Given options (17, 10, 30, 11), we might infer a potential scenario:

For instance, \( QM = MR = x \) and the total \( QR \) length is \( 2x = 34 \) if \( QR \) is split equally and \( x = 17 \).
Or with another option, perhaps a property or length or constraint given would simplify \( x \times 2 \), etc.

For now, if we blindly assume potential given scenarios fitting one solution typically seen where options align one common if perhaps indirectly asked midpoint or equal distribution.

Hence, choose

**A. 17**

assuming typical such segment relationship implied without further specific diagram clarification correct alignment.
