It is 900/7 = 128.57 degrees (approx).
Each interior angle is approximately 128.57 * * * * * That is only true of a REGULAR heptagon. The question does not state that it is regular.

In a regular heptagon, each interior angle is 180o - 360o ÷ 7 = 1284/7o ≈ 128.57o;in a non-regular heptagon, one of the interior angles ("an interior angle") could be any value greater than 0o and less than 360o except 180o.

There is no such thing as a hectogon. A heptagon has 7 vertices. Each exterior angle of a regular heptagon is 360/7 degrees. So each interior angle is 180 - 360/7 = 128.57 degrees (approx).
A heptagon has 7 sides and 7 angles. The sum of the interior angles is 900°. If the heptagon is a regular heptagon, meaning all sides and angles are congruent, then the formula (180(n-2))/ n gives the individual interior angle measure. "n" is the number of sides in this case. In a regular heptagon, the interior angle measures 128 4/7 degrees.
It is 128.57 degrees (approx). 900/7 degrees, exactly.
