The measures of the interior angles in a polygon are consecutive integers. The smallest angle measures 136 degrees. How many sides does this polygon have?

Expert Answer
If a polygon has n sides, then sum of interior angles is (n-2)×180
Given polygon's smallest interior angle is 136° and they are consecutive integers.
Hence n angles are in A.P with common difference 1
sum of the angles = (n/2)[ 272 +(n-1) ] = (n-2)×180 ..................(1)
By solving eqn.(1), we get n = 9
