Question

question 5 of 10 what is the measure of arc ac? a. 132° b. 138° c. 48° d. 42°

Explanation:

Step1: Recall arc - angle relationship

The measure of an arc is equal to the measure of the central angle that intercepts it. The sum of angles around a point is 360°.

Step2: Calculate the measure of arc \(AC\)

We know that the angle at the center corresponding to arc \(AC\) can be found by considering the given angles. The angle formed by the two right - angles and the \(42^{\circ}\) angle. The measure of arc \(AC=180^{\circ}- 42^{\circ}=138^{\circ}\)

Answer:

B. \(138^{\circ}\)
