The formula for finding the sum of interior angles of a polygon is:
Sum of angles = (n-2) � 180�
where n is the number of sides of the polygon.
In this case, the sum of angles is given as 1080�. We can set up the equation:
1080� = (n-2) � 180�
Now we need to solve for n:
1080� = 180�n - 360�
Add 360� to both sides:
1440� = 180�n
Divide both sides by 180�:
8 = n
So the polygon has 8 sides, which is option (b).

Degrees, then we can use the formula:
total angle sum = (n-2) x 180
where n is the number of sides in the polygon.
Substituting the given angle sum of 1080, we get:
1080 = (n-2) x 180
Simplifying, we get:
6 = n-2
n = 8
Therefore, the polygon has 8 sides.

To find the number of sides of a polygon given its total angle sum, we can use the formula:
Total angle sum = (n - 2) * 180�, where n is the number of sides of the polygon.
In this case, the total angle sum is 1080�, so we have:
1080� = (n - 2) * 180�
Divide both sides by 180� to solve for (n - 2):
6 = n - 2
Now, add 2 to both sides to solve for n:
n = 8
So, the polygon has 8 sides, and the answer is (b) 8 sides.
