Each exterior angle of a regular polygon of n sides exceeds by 6deg each exterior ngle of a regular polygon of 2n sides. Find an equation for n and solve it.
I believe it involves some of the facts like:
* All sides and angles of a regular polygon are equal.
* The sum of exterior angles equals to 360deg.
* Each interior + exterior angle equals to 180deg.
But I am still not sure how to construct an equation for this problem. I guess I am just weak at constructing simultaneous or similar linear equations.
