The sum of the angle measures of a polygon with s sides is 2,340. find s.
The sum of the angle measures of a polygon with s sides can be found using the formula:
Sum = (s-2) * 180
Given that the sum is 2,340, we can set up the equation:
2340 = (s-2) * 180
Dividing both sides by 180:
13 = s-2
Adding 2 to both sides:
s = 15
Therefore, the polygon has 15 sides.
