Thank you for the opportunity to help you with your question!

Answer choice C) 330 degrees.

I see that Z is the center of the circle.

We want measure of arc BAC

We know that arc BAC + arc BC = full rotation = 360 degrees.

arc BAC + 30 = 360

arc BAC = 360 - 30 = 330 degrees.

Please let me know if you need any clarification. I'm always happy to answer your questions.
