anonymous · Answer

sum of all interior angles = 180(n-2)
where n is the number of angles

anonymous · Answer

im still confused

anonymous · Answer

no problem ^_^

so you want to know, 'the sum of all the interior angles of the shape given'

the equation for this is: =180(n-1); where n is the number of angles in the shape the problem gives. so, how many angles are in the shape given to you, are there 4, 5, 6, how many angles are there?

anonymous · Answer

6

anonymous · Answer

yep,
so n=6
plug that into the equation,(below) and what do you get?
180(n-2) = ?

anonymous · Answer

i got 902

anonymous · Answer

It looks like the math become confusing for you, i'll show you ^_^

180(n-2) = 
180(6-2)=
180(4)=?
now try it from this step

anonymous · Answer

720

anonymous · Answer

yep, good work.
720 is the answer. 720 is the 'sum of all the interior angles of the shape given'

anonymous · Answer

thx

anonymous · Answer

ur welcome.

anytime you get a question that asks you about the 'sum of interiro angles of a shape' you can use that formula.
