Answer 6

Sum of the interior angles of a triangle = 180 degrees
Sum of the interior angles of a rectangle = 360 degrees
The sum of the angles of a pentagon is 540 degrees.
The sum of the angles of a hexagon is 720 degrees.
The sum of the angles of a heptagon is 900 degrees.
The sum of the angles of an octagon is 1080 degrees.
The sum of the angles of a nonagon is 1260 degrees.
The sum of the angles of a decagon is 1440 degrees.
Therefore;
11 sided figure = 1620 degrees
12 sided figure = 1800 degrees
13 sided figure = 1980 degrees
14 sided figure = 2160 degrees
15 sided figure = 2340 degrees
16 sided figure = 2520 degrees
17 sided figure = 2700 degrees <=== Answer!
