Well.. the equation for the interior angles of a polygon is 180(n-2). So it could possibly be 180.
Hope I could help.
First you would add 5/6 and 3/6 which would be 8/6. Next you would convert the improper fraction (8/6) into a mixed number which would be 1 2/6. Now just add 7 and 2 which is 9. Finally you would add the whole number and the mixed number. So your answer is 10 2/6 unless the instructions say to simplify then your answer would be 10 1/3.
