Question

what is the ratio between the sum of the interior angles of a regular Pentagon and a regular decagon.
pls show the working pls​

Answer 1

Answer:

Sum of interior angles of a polygon = (n-2)180

Sum of interior angles of a pentagon = (5-2)180 = 3×180 = 540°

Sum of interior angles of a decagon = (10-2)180 = 8×180 = 1440°

Ratio = 540:1440

              27:72

                3:8
