Given the horizontal and vertical projections of two planes ABC and ABDE.
A = 185 - 5 - 115
(a) Determine the dihedral angle between the planes.
(b) Draw the projections of the shortest horizontal line from C to the plane ABDE.
(c) On a separate diagram draw the projections of the skew lines AC and BD and show the projections of the shortest horizontal distance between them.
