Given:
A 7-sides regular polygon.
To find:
The sum of the interior angles of the given regular polygon.
Solution:
The formula for the sum of the interior angles of a regular polygon is:
[tex]Sum=180^\circ(n-2)[/tex]
Where, n is the number of sides of the regular polygon.
The given regular polygon has 7 sides. Putting [tex]n=7[/tex] in the above formula, we get
[tex]Sum=180^\circ(7-2)[/tex]
[tex]Sum=180^\circ(5)[/tex]
[tex]Sum=900^\circ[/tex]
Therefore, the sum of the interior angles of the given regular polygon is 900 degrees.
