Rewrite
I see that the most egregious aspects of the page's hideousness have been cleaned up.  However, problems remained in
spelling ("substitued")
usage ("reminds of", "allows to", "results into")
irrelevance of quoting the Law of Sines
nonsensical notion of "masking the irrationality".  "Rationalized units" are used in electrical units and Maxwell's equations, for a specific purpose.  But rationality of the items appearing in this theorem are irrelevant.
For this and other reasons (most importantly, the lack of an actual proof), I have rewritten this page.
