Problem of the Day #150: A Geometric Decagon August 16, 2011

Posted by Seungln in : potd , trackback

Albert is given a strange decagon. The ten angles, all convex, form a geometric sequence of ratio $r$. If $r$ is the maximum value possible and the decagon is not degenerate, find the first $10$ nonzero digits of $r$ in decimal form. The concatenated form of the answer will be the answer to this problem.
