Can someone please help me?

 

Two regular pentagons and a regular decagon, all with the same side length, can completely surround a point.



A square, a regular pentagon, and a regular n-gon, all with the same side length, also completely surround a point. Find n.

 

Thanks!

You can use the formula for the angles of a polygon.  The number of sides works out to 24.
