The sum of the angle measures of a polygon with n sides is 2880. Find n.
Solution:
In geometry, the definition of a polygon is given as a closed two-dimensional figure with three or more straight lines.
We see many different polygons around us.
For example, the shape of a honeycomb is a hexagon.
Each polygon is different in structure, they are categorized based on the number of sides and their properties.
Given, the sum of the angle measures of a polygon with n sides is 2880.
We have to find the number of sides n.
The sum of angle of polygon is given by the formula (n-2)180°
So, 2880 = (n-2)180°
Dividing by 180 on both sides,
(n-2) = 2880/180
(n-2) = 16
n = 16 + 2
n = 18
Therefore, the number of sides of a polygon is 18.
The sum of the angle measures of a polygon with n sides is 2880. Find n.
Summary:
The sum of the angle measures of a polygon with 18 sides is 2880.
