Answer 1

Answer:

You can put this solution on YOUR website! the exterior angle of a decagon is equal to 360/10 = 36 degrees. the internal angle of a pentagon is equal to 180 - 360/5 which is equal to 180 - 72 degrees which is equal to 108 degrees. ... the exterior angle of a pentagon is equal to 360/n, where n is the number of siges.
