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

Explanation:

Step1: Recall arc - central angle relation

The measure of an arc is equal to the measure of its central angle when the angle is measured in degrees.

Step2: Identify the central angle

The central angle corresponding to the given arc is $110^{\circ}$. So the measure of the arc is also $110^{\circ}$.

Answer:

A. $110^{\circ}$
