A pyramid is a solid figure with one face that is a polygon and three or more faces that are triangles with a common vertex. Yeah, pg. 114 in the math workbook is a little hard, and the guy who answered this before me thought it was funny to improve the answer by saying the answer was 45. That's just not mature. I don't get it. Anyway, I hope you finish your homework at this rate.
540 degrees. you figure it out by seeing how many triangles you can make in the polygon (without crossing lines), and, because triangles equal 180 degrees, you multiply 180 times how many triangles you can make.
