135°

A stop sign is a regular octagon which means it has 8 sides that have equal angles.

The formula:

$\frac{180 (n - 2)}{n}$ ${180(n-2)}/n$

n= number of sides
So now, we plug in 8 for $n$ $n$ and solve:

$\frac{180 (8 - 2)}{8}$ ${180(8-2)} /8$

$\frac{180 (6)}{8}$ ${180(6)} /8$

$\frac{1080}{8}$ $1080/8$

$135$ $135$
