How do I simply close a few widget windows? I am losing my mind trying to figure out how simply close widget that was so easy to open to begin with. 

[x] close button doesn’t seem to exist in this program so what’s a guy gotta do to close a window in blender 2.8? I also can’t close the widget with “transform | View | 3d cursor | annotations” window either.  I’m extremely frustrated and I’d really appreciate the help
Press T on your keyboard to open/close the Toolbar on the left, and N to open/close the Sidebar on the right.
