Answer:
Explanation:
The sum of the measures of the interior angles of a decagon (10 sided polygon) is 1,440. We found this by using the formula (n-2)(180). Thus, to find the measure of each interior angle we simply divide the sum by the number of total sides in the polygon. 1,440/10 = 144.
I dont know how to do this, but this is what g**gle had to say about the matter. I hope this helps?
