An awning is attached to a wall at a height "X".


The front edge is lower because the awning slopes by 15 degrees.


Depending on the width, the awning could extend by anything from 1m to 4m.

If I want the front edge at a specific height "Y", what would distance
"X" be?

I want to make up a spreadsheet to calculate this for any height "Y" and
any extension. So, if the client wants the front of the awning 2.1m off
the ground and it extends 2m, how high would "X" be?
