How to obtain alfa from the equation: cos(alfa)*R-sin(alfa)*L=R-h

How shall I transfer the equation: cos(alfa)*R-sin(alfa)*L=R-h ; to obtain angle (alfa) ?

Values: R,L,h are given

Thanks

This is a Quadratic Equation you can now solve for and from there you can solve for . Of course, since squaring has been required to get to this result, you will need to check if any of your solutions are extraneous.
