Construct a regular heptagon. On one non-adjacent side of the heptagon, construct a regular nonagon. On a non-adjacent side of the nonagon, construct a regular hendecagon (11-sided polygon). Continue to construct regular polygons in this way, where the number of sides increases by 2 for each new polygon, until you construct a regular tridecagon (13-sided polygon). How many sides does the resulting polygon have?
