How many degrees is the sum of the measures of the interior angles of a regular polygon with 14 sides?

To find the sum of the measures of the interior angles of a polygon, you can use the formula:

[

text{Sum of interior angles} = (n – 2) times 180°

]

where ( n ) is the number of sides in the polygon.

For a polygon with 14 sides:

[

text{Sum} = (14 – 2) times 180° = 12 times 180° = 2,160°

]

So, the correct answer is 2,160°.
