Question

Can someone please help me with this?

Answer 1

Since the measure of a full circle is 360°, subtracting a section will be;
360° - AB = ACB

`360-30=330`
So the measure of ACB is 330°.

Answer 2

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!
