Answer:A
Step-by-step explanation: The dotted line on the bottom is y> -3, the diagonal line is y<= -x.
The summation of the angle measures of a polygon is given by:
180(n - 2).
Thus, we need to find: 1800 = 180(n - 2)
10 = n - 2
n = 12
Therefore, the shape is a dodecagon, and the number of sides it has is 12.
