Question

a) The sum of the interior angles of a polygon is 540 How many sides does it have?​

Answer 1

each interior angle = 540 / n

each right turn going around angle = 180 - (540/n)

n exterior angles is all the way around, 360 degrees

n [ 180 - ( 540/n) ] = 360

180 n - 540 = 360

180 n = 900

n = 5
