GIven the horizontal and vertical projections of two planes ABC and ADE.
A = 140 - 100 - 10
(a) Determine the line of intersection between the planes.
(b) Determine the dihedral angle between the planes.
(c) Draw the plan and elevation of the perpendicular from D to the plane ABC. Hence or otherwise, determine the inclination of AD to the plane ABC.
(d) On a separate diagram, draw the projections of the skew lines AB and DE and show the projections of the shortest horizontal distance between them.
