HELP ME ASAP :)) How many sides does a polygon have if its total interior angle sum is 4 times its total exterior angle sum?

Step-by-step explanation:

If you are given the interior angle, just subtract that from 180 to get the exterior angle and then use the number of sides = 360 / exterior angle to find the number of sides. it's much easier. the number of sides is equal to 10. the sum of the interior angles is equal to 10 * 144 = 1440 degrees.
