(a) Find the equation for the line through the point(2,0,2), parallel to the planex + y + z = 10and orthogonal to the liner(t) = 1 + t, 1 t, 2t

(b) LetAdenote the angle between the planes2x + 2y + z = 1andx + 2y + 2z = 2. The planes intersect in a lineL.Find the plane that containsLand forms an acute angle,A/2, with both planes.
