Your answer is incorrect. Remember that there is a constant you need to use, in calculating your final answer, in order to get the units to come out correctly (in degrees, in this case). As a good check, the same object should have a smaller angular size when it is further away. At twice the distance, for example, it should have twice the angular size.
