Question

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

Explanation:

Step1: Recall circle - angle property

The sum of angles around a point is 360°.

Step2: Calculate the measure of the arc

Let the measure of the unknown arc be $x$. We know that one angle is 110°. So, $x + 110^{\circ}=360^{\circ}$. Solving for $x$, we get $x = 360^{\circ}-110^{\circ}=250^{\circ}$.

Answer:

D. 250°
