What does the Sexagesimal System use to measure angles?

1. 400 Grads

2. 360° or 21,600'

3. 2π Radians

4. 6400 Mills

The correct answer is: 360° or 21,600'

The Sexagesimal System is a traditional method of measuring angles that uses degrees as the primary unit, with one full circle divided into 360 degrees. This division is rooted in historical practices and is widely accepted in various fields, including land surveying. Each degree can be further divided into minutes and seconds, leading to the full representation of angles in degrees, minutes, and seconds, with one degree equating to 60 minutes and one minute to 60 seconds. Consequently, a complete circle in the Sexagesimal System is expressed as 360 degrees or 21,600 minutes, highlighting the significance and accuracy provided by this system in practical applications such as surveying and navigation. The reference to 400 Grads is related to a different angular measurement system known as the Gradian or Gon system, which is not part of the Sexagesimal System. Meanwhile, the mention of 2π Radians pertains to the Radian system used in advanced mathematics and trigonometry, while 6400 Mills is specific to certain surveying contexts but does not correlate with the conventional Sexagesimal System of angle measurement.
