Find parametric equations for the line through the point (0, 1, 2) that is parallel to the plane x + y + z = 2 and perpendicular to the line x = 1 + t, y = 1 - t, z = 2t. (Use the parameter t.) ( x (t ) , y (t ) , z(t) ) = Need Help? Watch It Consider the following planes. x +y +z= 4, x+ 9y+92= 4 (a) Find parametric equations for the line of intersection of the planes. (Use the parameter t.) ( x (t ) , y (t ) , z(t) ) = (b) Find the angle between the planes. (Round your answer to one decimal place.)
