Best ResponseYou've already chosen the best response.1for plane ... find the direction of normal (or Direction Cosines) for two lines ... solve them to find parametric eqn or reduce them to (xa)/l = (yb)/m = (zc)/n where l,m,n are direction cosines ... since you have direction cosines of both ... you can find the angle between them
