Question

what is average (arithmetic mean) of the measure of the five angles in a pentagon?
​

Answer 1

Answer:

Here's a pentagon, a 5-sided polygon. From vertex A we can draw two diagonals which separates the pentagon into three triangles. We multiply 3 times 180 degrees to find the sum of all the interior angles of a pentagon, which is 540 degrees.
