Sorry, just not seeing it. I read my interpretation in post #34 as consistent with post #1 (which is unclear) and post #20.That is exactly the issue I raised in Post #19! That part of the question conflicts with the information about angle θ.
Check the OP's reply in Post #20.
The question is badly written. I'm basing my responses on the OP's interpretation – but, yes, that could be wrong.
