Solving a firing-with-prediction puzzle in the game I am developing I found myself looking on the internet of solutions about triangle and its side. It turns out there is very few information about quotient of two sides.

enter image description here

Let ABC be a triangle. AB = a, CB/AC = b, ∠CAB = alpha. I need to find AC.


1 Answer 1


$CB = AC \cdot$ b $= xb$. Now use the law of cosines.
