Ricky is bored in math class and stands his textbook on so the cover is facing towards the blackboard on his flat desk. The book is 11 inches tall and 1.5 inches wide. He finds that if he pushes it a little at the top, it will wobble back and forth, but stay upright. But if the edge rises more than 1/8 inch off the table, the book will fall over. What is the smallest angle the face of the book can make with the table without falling over?
