If the measure of each interior angle of a regular polygon is 150, find the number of sides of the polygon. Previously we identified the number of sides in a polygon by taking the sum of the angles and using the S=(x-2)*180 formula to solve. But, this time we only know the measu...

Interior angle of polygon are in A.P.If the smallest angle is 120^@ and the common difference is 5^@, find the number of sides of polygon.
解析 We can show that the sum of all angles in a convex n - polygon is equal to 180(n-2) degrees (why ?).Therefore, each interior angle of a regular n-polygon measures (180(n-2))/n degrees.From the equation (180(n-2))/n=156, we get n=15. ...
