Exterior Angle= 360/no. of sides (so you're right! :))

Interior Angle =180-exterior angle

OR

Sum of Interior Angle= (no. of sides-2)*180

Then divide by the no. of sides

I personally use the first one because its easier to remember but they both work out fine!

interior angle is (n-2)x180 divided by n

exterior angle is 360 divided by n

n is the number of sides

I think this is right sorry if its not
