 # Trigonometry help

Hi all.

It’s been a long time since I’ve studied trigonometry, and I need a little help with something. I need to find out how to calculate one of the angles of a right triangle. I already know the lengths of all the sides, but I’ve forgotten how to calculate the angles. Can anyone help me?

Thanks for the link. Unfortunately, I’m actually writing a program and need to be able to calculate the angle dynamically, so I need the formula.

x is the angle you’re trying to find:

sin (x) = opposite/hypotenuse
