Can anyone provide the equation of calculating an edge angle using only the dimensions of the triangle without knowing any angles, I want to know this for my new TTi system of sharpening. It's been over 13 years since leaving school so this area of my mathematics is quite minimal...I am fairly sure at least of the soh, cah, toa acronym holds true, but be damned if I can remember how to use it espceially using a mobile phone calculator...which operaters differently to the logic operated system (which had it's own name at the time) I was used to using at school.
I have searched google a little, but as I am using my mobile phone as my modem data charges can be quite excessive, and I cannot afford them.
My triangle sizes are thus...roughly measured
Adjacent = 132mm
Opposite = 40mm
Hypotenuse = 148mm
If you can be bothered to calculate this for me I would appreciate it...but also leave me the formulae please.
Thanks
