  37. Purpose.-The purpose of this section is to familiarize the student airman with angular measurements and how they are used in determining directions in the U.S. Army Air Forces.
  38. Angle and units of angular measurement.-a Consider a circle. The circumference, or any part of that circumference which is called an arc, is divided into units called degrees. There are 360 degrees in a complete circumference (or one revolution). For more accurate measurements a degree is divided into 60 equal parts called minutes and a minute is divided into 60 equal parts called seconds.

Transcription Notes:
1. don't know if I needed to transcribe the graph further (im pretty sure you dont need to) 2. is there any way to do a subscript of 2? (i just copy and pasted, i think i'll do that from now on) (PS great job!!) (Nice work!)
