Question

points e, f, and d are located on circle c. the measure of arc ed is 108°. what is the measure of angle ecd? 72° 54° 126° 108°

Explanation:

Step1: Recall the central - angle theorem

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

Step2: Identify the relationship

Angle \(ECD\) is a central angle that intercepts arc \(ED\).

Answer:

\(108^{\circ}\)
