They are all 60 degrees.
The sum of the angles in ANY triangle (equiangular or not) is 180 degrees.
Use a protractor and you'll find that the 3 interior angles add up to 180 degrees and that the 3 exterior angles add up to 360 degrees
With a protractor remembering that interior angle and exterior angle add up to 180 degrees because angles on a straight line add up to 180 degrees. The 3 interior angles of any triangle add up to 180 degrees and their 3 exterior angles add up to 360 degrees.
The formula is: (20-2)*180 = 3240 degrees which is the total sum of interior angles
