Answer:

1080 degrees.

Step-by-step explanation:

The sum of the exterior angles of all polygons add up to 360 degrees

So this polygon has  360 / 45 = 8 sides and 8 interior angles.

Each interior angle = 180 - 45 = 135 degrees ( adjacent angles).

So the sum of the interior angles = 8 *135 = 1080 degrees.
