27, 33, 39, 45 (Use CalcPlot3D for problems 27, 33, 39,and 45. On problem 27 include 4 tangent lines).

could you help me sketch these 4 with cal plot3d: https://c3d.libretexts.org/CalcPlot3D/index.html

thank you so much

Perpendicular Tangent Planes In Exercises 45 and 46, (a) show that the surfaces intersect at the given point and (b) show that the surfaces have perpendicular tangent planes at this point. 45. z = 2xy?, 82 - 5y2 - 8z = -13, (1, 1, 2) 39. z = x2 - xy + yz - 2x - 2y Finding the Angle of Inclination of a Tangent Plane In Exercises 33-36, find the angle of inclination of the tangent plane to the surface at the given point. 33. 3x2 + 2y2 - z = 15, (2, 2, 5) Finding the Equation of a Tangent Line to a Curve In Exercises 27-32, find a set of parametric equations for the tangent line to the curve of intersection of the surfaces at the given point. 27. x2 + y? = 2, z = x, (1, 1, 1)
