the ratio of the sum of the angles of a triangle to the sum of the interior angles of a pentagon

Sagot :

Lemme tell you the formula on how to get the sum of the interior angles of a polygon tho. ☺

To know the sum of the interior angles of a polygon, we use the formula..
180 (n - 2) where n is the number of sides.

180 (3 - 2) = 180 (1) = 180 - sum of interior angles of trigon
180 (5 - 2) = 180 (3) = 540 - sum of interior angles of pentagon

180 : 540 = 1 : 3
