OpenStudy (anonymous):

so 108

OpenStudy (anonymous):

wait so is the problem 180-n2 or is it power 2?

OpenStudy (anonymous):

that is a 72 not a n2

OpenStudy (anonymous):

HAHAH oh ok thanks!

OpenStudy (anonymous):

it's 72 because you take 360 and divide by the number of middle angles (you can see that there are 5 in the drawing)
