Answer: 1080 </h3>
====================================================
Explanation:
We have an octagon because there are n = 8 sides. The diagram below shows one way to number the sides so you can count them efficiently (without missing any or double counting any).
----------------
Plug n = 8 into the formula below
S = 180(n-2)
S = 180(8-2)
S = 180(6)
S = 1080
The 8 interior angles add up to 1080 degrees.

Answer:
4.4%
Step-by-step explanation:
solution:
principal (p) = $300
time(t) = 3 years
interest (I ) =$40
rate (r) = ?
we know that,
I = (PTR)/100*
OR, 40 = (300 *3 * R)/100
or, 40 = (900R)/100
or, 40 = 9R
or, 40/9 = R
or, R = 4.4%
Rate(r) =4.4%
