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.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
