Question

value: 1
find the measure of the arc.
110°
?
a. 110°
b. 55°
c. 70°
d. 250°

Explanation:

Step1: Recall circle - angle property

The sum of central - angles in a circle is 360°.

Step2: Calculate the measure of the arc

Let the measure of the unknown arc be \(x\). We know that one central - angle is 110°. So, \(x + 110^{\circ}=360^{\circ}\). Then \(x=360^{\circ}-110^{\circ}\).

Answer:

D. 250°
