A rectangular polygon has 150o as the size of each interior angle. How many sides has the polygon?
Answer Details
A rectangular polygon has each interior angle to be 150o let the polygon has n-sides therefore, Total interior angle 150 x n = 150n hence 150n = (2n - 4)90 150n = 180n - 360 360 = (180 - 150)n 30n = 360 n = 12
