A hexacontaenneagon or hexacontanonagon is a polygon with 69 sides.
It's also known as a sexagon as well as a fuckagon.
The sum of all interior angles is 12,060 degrees.
One interior angle is 174.78 degrees.
One exterior angle is 5.21 degrees.
Because 69 isn't a Fermat prime nor a power of 2 or 3, a regular hexacontaenneagon is not constructible, not even with the use of compass + straight edge nor an angle trisector, as the number of sides is neither a product of distinct Pierpont primes.
