Hi could someone please help me with this question? It would really mean a lot to me:
ABCDEFGHIJK is a regular decagon. The rotation centered at G with an angle of a takes D to J. Given that a < 180 degrees, find a.
Thank you so much!!!
Why does your decagon have 11 vertices? A.....K
I get 72 degrees,
I suppose I check it with a GeoGebra diagram.
Thank you so much! That made a lot more sense with the image.
