9514 1404 393

Answer:

Step-by-step explanation:

The relationship between sides and the sum of angles is ...

sum of angles = (sides - 2)·180°

Filling in the given value and solving for "sides", we get ...

5220 = (sides -2)180

29 = sides -2 . . . . . . . . . divide by 180

31 = sides . . . . . . . . . . . . add 2

The polygon has 31 sides.
