A.
20°

B.
162°

C.
180°

D.
3240°

Answer 2

i think its B

Answer 3

exterior always 18, and it must come up to 180...So 162. thats how i got it

Answer 4

Use the formula again:

180 * (n - 2)

n = sides, so we plug in 20:

180 * (20 - 2)

180 * 18

Answer 5

Oh, my bad..that's for the sum of all the measures.

Answer 6

But do it anyway, we can divide 20.

Answer 7

What's 180 * 18?

Answer 8

Nvm, you're correct.

Answer 9

180 * 18 = 3420

3420 / 20 = 162

Answer 10

3240 / 20 = 162
