Question
The image displays a circle with a central angle and an inscribed angle. Here is a detailed description:

- The circle has a central point where two radii intersect, forming a central angle marked as 110°.
- A line extends from point A to B, forming a chord.
- An inscribed angle, ∠AXB, is formed with vertex A on the circumference.
- This inscribed angle is labeled with a variable, \( x^\circ \).

**Explanation of the Diagram:**

1. **Central Angle (∠AOB):** The angle subtended at the center, marked as 110°.
2. **Chord AB:** A straight line connecting two points on the circle's circumference.
3. **Inscribed Angle (∠AXB):** This angle is subtended by the same chord AB but with its vertex at point A on the circle's circumference. 

**Key Concept:**
- The inscribed angle (x) is half the central angle when both angles subtend the same arc. Therefore, \( x = \frac{110^\circ}{2} = 55^\circ \).
