When you use a protractor to measure an angle, the reported measurement is rounded to the nearest degree. However, some measurements must be more precise. You can make more precise measurements using smaller units of measure. For example, 1° equals 60 minutes (60'), and 1' equals 60 seconds (60"). The measurement 75° 20' 48" represents 75 degrees, 20 minutes, and 48 seconds, or 75 + 20/60 + 48/3600 - 75.347 degrees. Express each measurement in degrees, rounded to the nearest thousandth. (a) 23° 15' 30" (b) 20° 30' 50" (c) 5° 20' 35"
