Respuesta :

We know, the measure of whole circle = 360
So, ACB = 360 - AOB
ACB = 360 - 30
ACB = 330

In short, Your Final Answer would be Option A

Hope this helps!

Since the measure of a full circle is 360°, subtracting a section will be;
360° - AB = ACB
[tex] 360-30=330 [/tex]
So the measure of ACB is 330°.
