The key to solving the problem is to see that angles CDA and CBA are congruent, because they both cut off the same arc AC.

Then in triangle DAX you know the measures of angles AXD and ADX; knowing that the sum of the three angles is 180 degrees makes it easy to find the measure of angle DAX.

I leave the simple calculations to you.
