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 … WebRule: The exterior angle = \dfrac {360\degree} {\textcolor {red} {n}} where \textcolor {red} {n} is the number of sides. The sum of all the exterior angles will equal 360\degree. For the triangle shown, we can see it has \textcolor {red} {3} sides, so to calculate an exterior angle we do: \dfrac {360\degree} {\textcolor {red} {3}} = 120\degree roland w. monja https://0800solarpower.com
