 Question 569498: Hi, 1. suppose that the sum of the measures of the vertex angles of a polygon is 1620 degrees. How many sides does the polygon have? what I've tried: (n-2)180/n= i multiplied "n" by both sides to cancel out the fraction and then use distribution property to fix the equation. 180n - 360= 1620n -180n 180n -360= 1440n -0.25=n but that is the wrong answer. the book says that the answer of sides is 11.
