Find the number of sides of a regular polygon with each interior angle equal to 157.5°. the regular polygon has sides.

The interior angle plus the exterior angle totals to 180 so you would take 180 and subtract 157.5 and get 22.5
next you would take 360 for the total of degrees that he external angles totals up to.
so 360 divided by 22.5 equals the number of sides you shape has and that would be 16 sides.

Step-by-step explanation:

This the -2 only have to multiply by 4 because we can't multiply it by the same number so four is the next number that are even number so we get 8
