Answer:
72 degrees
Step-by-step explanation:
Find the diagram attached. We are to find the length of the arc
Measure of arcABC = rtheta
16π = 10 theta
theta = 16*180/10
theta = 16 * 18
theta = 288degrees
central angle = 360 - 288 = arc AC
central angle = 72degrees
Hence the arc measure of AC is 72 degrees
