OK....the formula is (n-2)*180 where n is the number of sides....

superdavesuper · Answer

so what do u think is the answer to b?

superdavesuper · Answer

come on @yacoub u can do it - I give the answer to part a already, what do u think is the answer to part b?

yacoub1993 · Answer

@superdavesuper  i didnt understand what n-gon means

superdavesuper · Answer

n-gon means it is a polygon with n sides

yacoub1993 · Answer

ok then

superdavesuper · Answer

answer to part a is (n-2)*180

yacoub1993 · Answer

i am still not getting to solve it

yacoub1993 · Answer

i am getting frustrated

superdavesuper · Answer

relax :) do u understand the answer I gave for part a?

superdavesuper · Answer

hmmm...not sure i can find a better way to explain this....

yacoub1993 · Answer

ooooh thnxs for trying to help

bibby · Answer

n is a variable number that represents the sides.
as such 180*(n-2) represents the sum of the angles of a regular n-gon.

what don't you get?
