If the sum of the interior angles of a polygon is , how many sides does the polygon have?
A
B
C
D
Verified step by step guidance1
Recall the formula for the sum of the interior angles of a polygon with \( n \) sides:
\[ \text{Sum of interior angles} = (n - 2) \times 180^\circ \]
Set the given sum of interior angles equal to the formula:
\[ 1080^\circ = (n - 2) \times 180^\circ \]
Divide both sides of the equation by \( 180^\circ \) to isolate \( n - 2 \):
\[ \frac{1080^\circ}{180^\circ} = n - 2 \]
Simplify the left side to find \( n - 2 \):
\[ 6 = n - 2 \]
Add 2 to both sides to solve for \( n \):
\[ n = 6 + 2 \]
