Answer:
C
Step-by-step explanation:
Hello There!
If you look at the image you can see that an inscribed angle is equal to one half of the major arc minus the minor arc
So for this problem here
m∠CAD would be equal to 1/2 (arc CD - arc BD)
so now we just plug in the values
m∠CAD = 1/2 ( 210 - 72)
210-72=138
138/2=69
so m∠CAD = 69
