Answer: 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
