How to calculate the height of a bookstand at 20 degrees.

I have two pieces of wood.
One is the base of a bookstand that will sit on a desk.
The other piece will be hinged with the other at their front and will support the book.
It is 11 1/4 inches from the hinge to the back of the board.
How high should the back of the board be for a 20 degree angle?

Rather than set a defined 20 degree angle, move the back of the board up until you find the reading angle to be comfortable.  Then measure the height.  You will probably find that 20 degrees is not a comfortable angle, and want something more like 45 or 50 degrees.

Thanks for the suggestion on adjusting for reading, but in this case, I will be making notes in the book for revisions.
A steeper angle and I find it hard to write.
I have found 20 degrees to be the best angle for being able to write on a book.

A miscellany is defined as a "collection of various pieces of writing by different authors", but it has come to mean something "Of items gathered or considered together of various types or from different sources" or "a collection or group composed of members or elements of different kinds". The word "miscellaneous" comes from the Latin word "miscere", meaning "to mix." You might have heard the expression "a mixed bag," which applies when you don't quite know what you're going to get. More commonly, a miscellaneous group is made up of an odd group of things that don't fit anywhere else.
