Question

question 2 of 10
what is the sum of the measures of the interior angles of a heptagon?
a. 360°
b. 900°
c. 1440°
d. 1260°
e. 45°
f. 1080°

Explanation:

Step1: Determine number of sides

A heptagon has 7 sides, so \( n = 7 \).

Step2: Apply interior angle sum formula

Sum = \( (n - 2) \times 180^\circ \). Substitute \( n = 7 \): \( (7 - 2) \times 180^\circ = 5 \times 180^\circ = 900^\circ \).

Answer:

B. 900°
