The sum of the measures of all the exterior angles of any convex polygon is 360 degrees.
If the polygon is regular and has n sides, the measure of each exterior angle is 360/n degrees.
Do the arithmetic for n=72....

You can put this solution on YOUR website! To find the measure of an exterior angle of a polygon, use these formula in this order.
In this case, s is the sum of the interior-angle measurements of the polygon, and e is the measure of an exterior angle of the polygon.
Let n be 72.
Then, solve (72 - 2).
72 - 2 = 70
Next, multiply the difference by 180.
70 * 180 = 12,600
Now, divide the product by 72.
12,600 ÷ 72 = 175
Finally, subtract the quotient from 180.
180 - 175 = 5
So, the measure of each exterior angle of a regular 72-gon is 5°.
