Answer
135 degrees
Work Step by Step
First, we use the formula to find the total degrees in a given polygon:
$(n-2)180$ Where n represents the number of sides.
We then substitute $n$ for 8, $(8-2)180$.
This gives us 1080.
Finally, we divide by 8, since the polygon in question has 8 angles.
$1080\div8=135$
