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 - arc relationship

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

Step2: Identify angle ECD

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

Answer:

\( 108^{\circ} \)
