I see, you started a new thread about a puzzle in a different thread 8-)

Indeed. And the solution to this formula is "supposed to be" 30 degrees, so that it validates the trig-based answer to the puzzle.
FWIW, the source's instructions (but not the instructions in the puzzle thread) say NOT to use trig, and to use geometry instead.

Who cares. This is the math forum. It is sufficient that an answer exists and is unique. Furthermore WolframAlpha gives you an exact expression... who would you ever need more ? :)

Could you please show me the source's instructions ?

You may use only elementary geometry, such as the fact that the angles of a triangle add up to 180 degrees and the basic congruent triangle rules (side-angle-side, etc.). You may not use trigonomery, such as sines and cosines, the law of sines, the law of cosines, etc.]

Thanks. Trigonometry can solve both problem 1 and 2 !
