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°

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
