Pls answer. will mark as branliest

 135°

Step-by-step explanation:

First, let's find the sum of the interior angles of an octagon (8-sided polygon).

S = 180(n - 2)   where n = 8

S = 180(8 - 2)

S = 180(6)

S = 1080

Next, to find ONE angle, divide the sum by the number of angles in the polygon (octagon has 8 angles)

I = S/n

I = 1080/8

I = 135

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !

i would say c is the best answer, hope it's right!

good luck! =)
