Answer:

20-gon

Step-by-step explanation:

First we start with the formula to find what the sum of angles will be if we know the number of sides.

S=(n-2)*180 where S is the sum of angles and n is the number of sides.

Normally you'd plug in n to find S, but you can do the opposite too.

3240=(n-2)*180

Let me know if you need help working it from here.
