Question

how many degrees does a heptagon has

Answer 1

Heptagon: 900

In general:  

n-agon: (n-2) * 180

A heptagon is a polygon of seven angles. Each of the sides can be the same length or can be of seven different lengths. If the sides are of unequil length, the angles will not all be the same. No matter how many different angles you have, they will all add up to 360 deg. This is true of any polygon.
