Question

sum of interior angles.
pentagon
number of sides:
sum of interior angles: ______ °

Explanation:

Step1: Determine number of sides (n)

A pentagon has 5 sides, so \( n = 5 \).

Step2: Apply sum formula

Sum of interior angles = \( (n - 2) \times 180^\circ \). Substitute \( n = 5 \): \( (5 - 2) \times 180^\circ = 3 \times 180^\circ = 540^\circ \).

Answer:

540
