top-center: circle diagram with center C, radii CA and CB forming a 115° central angle; position of the minor arc is A to B on the right side of the circle, and the intended arc-measure answer is 115°.
center: second circle diagram labeled O with points A, B, C on the circumference; angle x is at A between chords/segments AB and AC, and arc BC is marked 41° near the bottom, with a likely relation x = 20.5° from the inscribed angle theorem.
1. **Problem 1: Name the minor arc and find its measure.**
Given a circle with center C and points A and B on the circumference, the central angle \(\angle ACB\) measures $$115^\circ$$.
- The minor arc is the arc intercepted by the central angle, which is the arc from A to B, denoted as $$\widehat{AB}$$.
- Since the central angle measures $$115^\circ$$, the measure of the minor arc $$\widehat{AB}$$ is also $$115^\circ$$.
**Answer:** The minor arc is $$\widehat{AB}$$ and its measure is $$115^\circ$$.
2. **Problem 2: Find \(x\) in circle O.**
Given:
- Circle with center O.
- Points A, B, C on the circumference.
- Arc $$\widehat{BC}$$ measures $$41^\circ$$.
- Angle \(x\) is an inscribed angle at point A intercepting arc $$\widehat{BC}$$.
**Step 1:** Recall the inscribed angle theorem:
$$x = \frac{1}{2} \times \text{measure of intercepted arc}$$
**Step 2:** Substitute the given arc measure:
$$x = \frac{1}{2} \times 41^\circ$$
**Step 3:** Calculate:
$$x = 20.5^\circ$$
**Answer:** $$x = 20.5^\circ$$.
