Answer:
In order to find the value of the interior angle of a regular polygon, the equation is (n−2)180∘n where n is the number of sides of the regular polygon
Hope that helped
If a pentagon is regular, then all of the sides are the same length. This means that
So, if 
, the lengths of the sides evaluate to
So, all the sides of the pentagon are 21 units long, and AB is 21 units long as well, because all sides are the same length.
