Tetradecagon - Triangle problem

[jasoncameron]

The above Tetradecagon is made up of 14 Right triangles. Each side of the Tetradecagon is 5.25cm

The circumradius of the Tetradecagon is 11.8cm

Is it possible to determine the lengths of the the other two sides of the triangles knowing this information? If so What are the dimensions of the triangles that make up this polygon.

Thanks, Jason!

Notice that the inner figure is also a regular tetradecagon. The sides of the triangles are extensions of sides of

the inner tetradecagon. What would be the angles between those sides?

solution

I was able to determine the solution with measuring tools instead of Math so it is not possible to show my work.
This was not a homework project for me but necessary measurements for something I am building.
