Hi Danny,

I used your info to help a friend today!

I was wondering if you could tell me how to reverse engineer to get the angle from the distance 1 value. I know MoI can just use 2 distances, but if I want to know the angle I just created, I would like the math. I also know MoIcan tell me what the angle is, but was just wondering if you knew the formula to go the other way?

Thanks again.

Hi Burr,

I'm not exactly clear on what your asking, you need to know 2 values of a right angle triangle to find the unknown, so if you have 2 known distances you can calculate the angle. If you have an angle and a distance you can calculate the unknown distance.
I've attached a trigonometry example sheet which shows the formulas used for the different knowns and unknowns.

Is this what you meant ?

Cheers

That covers it D. Sorry to ask you to be my math teacher. I do appreciate it.
