Question

find the measure of the arc. ? 55° 46° a. 46° b. 55° c. 110° d. 125°

Explanation:

Step1: Recall central - angle and arc - measure relationship

The measure of an arc of a circle is equal to the measure of its central angle.

Step2: Identify the central angle for the arc in question

The central angle corresponding to the arc in question is \(55^{\circ}\). So the measure of the arc is also \(55^{\circ}\).

Answer:

b. \(55^{\circ}\)
