the sum of the polygon is 1980 degree .what is the sum of the angles of a polygon with one side less? what about a polygon with one side more​

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

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
