OpenStudy (dan815):

ok look at this

OpenStudy (dan815):

OpenStudy (dj3strella):

yes

OpenStudy (dan815):

how many?

OpenStudy (dj3strella):

OpenStudy (dan815):

-.-

OpenStudy (dan815):

Or you can do the simpler way and get square and see but only works in some cases

OpenStudy (dj3strella):

t=133 u=94 v=111 r=107

OpenStudy (anonymous):

interior angles is (n-2)*180 therefore, 540 - (133+94+111+107)= answer

OpenStudy (dan815):

in particular u can always form for a n sided polygon n-2 triangles

OpenStudy (dan815):

which is where that (n-2)*180 is coming from

OpenStudy (anonymous):

finding the interior angles

OpenStudy (dj3strella):

is it 95

OpenStudy (anonymous):

I think so

OpenStudy (dj3strella):

and this one @Mvpriest
