Question 385321
There's a formula to find the angle total of a polygon if you know n, the number of sides.


Angle Total = (n-2) * 180


For this question, you know the angle total is 5400, so solve for n:


5400 = (n-2) * 180
5400 / 180 = n-2
30 = n-2
n = 32


So the polygon has 32 sides. It is called an Icosidodecagon, and you can view it here:
