Can someone explain how to do this problem correctly

Answer:

88 degrees.

Step-by-step explanation:

The circle in question must be equal to 360 degrees if arc CDA is equal to a number greater than 180.

If 360 degrees is the total measure, and arc CDA is equal to 272 degrees (Which I noticed you placed wrong, it should be in the bigger half of the circle rather than the little half.).

So to get your final answer, you subtract 272 from 360.

360 - 272 = 88 degrees.
