Question

find the number of the sides of the regular polygon which is each of the it's angles is 135
​

Answer 1

Answer:

Step-by-step explanation:

If the interior angle is 135 degrees then the exterior angle is 180–135 = 45 degrees. This is because an exterior angle added to the interior angle must form a straight line. The exterior angles of all regular polygons must add up to 360 degrees and therefore the number of exterior angles must be 360/45 = 8.
