h/ 5+x would appear h / (5+x)
h / b -5 would appear h /(b-5)
Nothing to be confused about.
tan is opposite side / adjacent side .......that's it.
No matter how you come up with the measurements of the sides, as long as you carefully follow tan = opp/adj, then you're okay.
Opsss, I'm wrong!
After reading masters' reply (which is correct), I am wrong with mine.
tan(32 deg) cannot be h /(5 +x) nor h /(b -5)....because h is not the opposite side of 32 degrees.
Must be that I just woke up.
Still, I shouldn't have missed that tan(32 deg)....
Sometimes, though, I like being wrong. :-)
