HELP PLS!!

Find the measure of each interior and exterior angle of a regular 40-gon.

All exterior angles will add up to 360 degrees, regardless of the number of sides.

For the sum of the interior angles, use this formula:

The sum of the interior angles = (N x 180) - 360

Where N = the number of sides

So, (40 x 180) - 360 = 6840 degrees

x=153

Step-by-step explanation:

5tests-85 average score

9tests-x average score

Cross multiply

5x=85×9

5x=765

Divide both sides by 5

x=153

Therefore,x=153
