Answer:
The arcs form a circle ⇒ answer C
Step-by-step explanation:
* Lets explain some facts in the circle
- The chord in a circle is a segment whose endpoints lie on the circle
- Any chord of a circle intersects it into 2 arcs
- The minor arc which its measure lies between 0° and 180°
-The major arc which its measure lies between 180° and 360°
- The sum of the measures of the minor arc and the major arc is equal
to the measure of the circle
- The measure of the circle is 360°
* Lets solve the problem
∵ The measure of arc XY + the measure of arc YZX = 360°
∵ The arcs do not overlap
- That means the endpoints of the arcs are X and y
∵ The measure of the circle is 180°
∴ The arcs form a circle
