Respuesta :
s=15
Whatever the number of sides of a polygon,
the sum of its exterior angles is always 360∘
Further, each pair of exterior angle and interior angle adds up to 180∘
Hence in a polygon with s sides (or angles),
the sum of all the interior and exterior angles would be 180∘×s
and sum of interior angles would be 180∘×n−360∘=180∘(s−2)
As sum of angles is 2340∘
Hence, 180(s−2)=2340 or s−2=2340180=13
and s=13+2=15 and polygon is a Pentadecagon.
i hope u understand :)
ANSWER
[tex]s = 15[/tex]
EXPLANATION
The sum of angles in a regular polygon with s sides is given by
[tex](s - 2) \times 180[/tex]
It was given that, the sum of the angle measures of a polygon is 2340.
This implies that;
[tex](s - 2) \times 180 = 2340[/tex]
Dividing through by 180, we get,
[tex](s - 2) = \frac{2340}{180} [/tex]
Simplify the right hand side to get;
[tex](s - 2) = 13[/tex]
We make s the subject to obtain,
[tex]s = 13 + 2[/tex]
Simplify to obtain;
[tex]s = 15[/tex]
Therefore the polygon has 15 sides.
[tex]s = 15[/tex]
