Me with these ? both
if each exterior angle of a polygon is 45 degrees, what is the sum of the interior angles?
hint: what do we need to know to find the sum of the interior angles of a triangle? what can we determine about a polygon from knowing the measure of each of its exterior angles

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.

idk this answer sorry cant on this one.

step-by-step explanation:

i think that you should ask google for the answer to that problem because if we don't know it google does
