Answer:

Sum of angles of a polygon with one side less = (12-2)x180 = 1800

Sum of angles of a polygon with one side more = (14-2)x180 = 2160

Step-by-step explanation:

(n-2)x180 = 1980

n = 13

Sum of angles of a polygon with one side less = (12-2)x180 = 1800

Sum of angles of a polygon with one side more = (14-2)x180 = 2160
