Answer:
135°
Explanation:
First, count the amount of sides on the stop sign. There are 8 sides on the shape so we substitute this into a formula that we use to find the sum of the exterior angles in a shape.
(n - 2) × 180°
So the formula would look like (8 - 2) × 180°. The final answer after using this formula would be 1080°. This is the sum of the interior angles in this shape.
Then we do 1080° ÷ 8 (number of sides) = 135°.
Therefore, each angle is 135°, as the shape is a regular octagon.
(Extra information: Even if it is a irregular octagon the sum of all the interior angles will be 1080°. But each interior angle is not guaranteed to be 135°.)
