I have an equation which I cannot solve. I have the values and the answer, but I am unable to recreate it myself. Any help would be appreciated as I need to apply this to my own numbers....
To calculate an angle (A) = tanH/(D-d)
Where H=1.5, D= 2.5 and d=0.5. The answer I have been given is 56 degrees.
I have tried every combination of things and am getting nowhere in recreating the answer, can someone tell me what I am doing wrong?
Thanks in advance,
