Use the image to answer the question.
An illustration shows two school crossing signs labeled Figure A and Figure B. The signs are pentagons. A silhouette of a walking man and woman are centrally located on the signs. Starting at the bottom left vertex of both figures, the vertices are labeled A, B, C, D, and E. A line inside Figure A connects the vertices B and D. A vertical perpendicular line extends down from the top vertex C to the base side A E. Lines inside Figure B connect the vertices A and C, B and D, and C and E.
Select the correct decomposition into triangles of the sign shaped as a pentagon.
Choose 1 for Figure A , 2 for Figure B , or 3 for both Figure A and Figure B .

I apologize for the confusion in my previous response. Based on the description provided, it seems that Figure B should be the correct decomposition into triangles of the sign shaped as a pentagon. The lines connecting the vertices form triangles in Figure B, whereas Figure A does not have any lines connecting the vertices to form triangles. Therefore, the correct answer is 2 for Figure B.

The sum of the interior angles of a hendecagon (11-sided polygon) can be found using the formula:
Sum of Interior Angles = (n - 2) * 180 degrees
where n is the number of sides of the polygon.
In this case, n = 11, so the sum of the interior angles is:
Sum of Interior Angles = (11 - 2) * 180 = 9 * 180 = 1620 degrees
Therefore, the sum of the interior angles of a hendecagon is 1620 degrees.
