Answer:
The polygon has 3 sides ( a triangle).
[tex]n=3[/tex]
Explanation:
The sum of the angles of a polygon can be written as;
[tex](n-2)180[/tex]
where n is the number of sides of the polygon.
Given that the sum of the angles in the polygon is 180 degree;
[tex]\begin{gathered} (n-2)180=180 \\ n-2=\frac{180}{180} \\ n-2=1 \\ n=1+2 \\ n=3 \end{gathered}[/tex]
Therefore, the polygon has 3 sides ( a triangle).
[tex]n=3[/tex]
