Convert each angle measure from radians to degrees. Round to three decimal places  Keystrokes: (5  /21) 2nd APPS 3 (5  /21) r ENTER (5  /21) r

Convert each angle measure from radians to degrees. Round to three decimal places   27 

There are 360  in each circle. Let’s assume this to be 1 

Each degree is broken up into 60 smaller parts called minutes. 1  = 60’

Each minute is broken up into 60 smaller parts called seconds. 1’ = 60’’

In summary… 1  = 60’ 1’ = 60’’ 1  = 3600’’
