Converting Angles to Decimal Degrees

This video is an honors precalculus final exam review focusing on converting angles from degrees, minutes, and seconds (DMS) to decimal degrees. The instructor explains the process of conversion using a calculator, detailing how to handle minutes and seconds by dividing them by 60 and 3,600, respectively. The video also covers rounding the result to the nearest hundredth of a degree. The tutorial concludes with instructions to apply the same method to subsequent problems.
