All closed figures have as a sum of interior angles the following formula N-2 x 180 thus a triangle has 180 sum interior angles pentagon (5) sided is 5-2=3 x 180= 540 sum interior angles..so for 11 sided closed shaped answer is 11 - 2 = 9 x 180= you have to at least do the multiplacation!! if you can't tell N=number of sides.....

lol are you in geometry? i think you should post this question in the math section but anywayz my geometry math final is tommorow and i think you have to use this: (n-2)(180) then you plug in 13 for n which is (13-2)(180); then its 11(180), and your answer is 1980 i think so make sure its right before you write it down!
