How to calculate the roll-pitch-yaw of a given plane

Dear everybody,

I have a plane whose equation is known (for example: ax+by+cz+d=0). Is it possible the calculate the roll-pitch-yaw angles of this plane?

just assume that one of the x,y,z is 0 in order to calculate the angles.

For example, for theta, which is the angle between x and y you can assume z=0 (it will be same result for any value of z, but for z=0 it is simplest). In this case, theta is the pitch.
