The external angle of a regular polygon is given by:
Where:
n: It is the number of sides of the polygon
Then, for a nonagon each exterior angle will measure:
Answer:
40 degrees each exterior angle
360 degrees the sum
For a geometric sequence with common ratio 
, we have
that is, the
-th term in the sequence is the product of the previous term and the common ratio . So
Then the sum of the first 7 terms is
Notice that
so we can subtract this modified sum from
to get
We're told that
