well it has to be an obtuse angle to have enough agles to add up to 3240, and the degree of the angles have to add up evenly so there cant be a decimal to have an whole amount of sides. cant be 90 degres caues theres only 4 and doesnt add to 3240
so i started making a table guess n check i got to 120 degrees which makes 27 even angles so theres 27 sides to this polygon with and angle of 120degrees
