WebAnish Jagagannathan. So if we know that a pentagon adds up to 540 degrees, we can figure out how many degrees any sided polygon adds up to. Hexagon has 6, so we take 540+180=720. A heptagon has 7 sides, so we take the hexagon's sum of interior angles and add 180 to it getting us, 720+180=900 degrees. Same thing for an octagon, we take … Web2 dagen geleden · 12-Sided Fidget Cube Dodecagon Fidget Toy for Children and Adults Stress Relief. $9.79. Free shipping.
