Applying the central angle theorem of a circle, the measure of arc CEB is same as the measure of angle GCB, which is: D. 231°.
What is the Central Angle Theorem?
Based on the central angle theorem, it states that the measure of an intercepted arc equals the measure of its central angle.
Measure of arc GEB = measure of angle GCB
m∠GCB = 51 + 90 + 39 + 51
m∠GCB = 231°
Measure of arc GEB = 231°
