In the DMS system, there are 360 degrees in a circle, 60 minutes in one degree, and 60 seconds in one minute. So converting 34.88° to DMS would be 34° 52' 48" (34 degrees, 52 minutes, and 48 seconds.) Why do you think this way of measuring angles exists? In what situation(s) would it prove to be useful?
