What is the sum of the interior angles of a heptagon ?

Let n be rhe number of vertices in the polygon, then the sum of all interior angle is (n - 2) × 180°.

Number of sides in a heptagon = 7

So, n = 7

So,

the sum of the interior angles of a heptagon

= (7 - 2) × 180°

= 5 × 180°

= 900°

i have no idea just need points sorry

step-by-step explanation:

the answer to this is a. a^2 + b^2 = c^2
