Question

what is the sum of all angles of a Pentagon​

Answer 1

Answer:

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.

Answer 2

The sum of all angles of a pentagon is 540 degrees mark me brainliest
