Given the horizontal and vertical protections of two planes ABCD and ABE.
A = 145 - 55 - 5
(a) Determine the dihedral angle between the planes.
(b) Show the projections of a line drawn from E which shall touch the plane ABCD at a distance of 90 mm from E and which shall be inclined at 45° to the horizontal plane.
(c) On a separate diagram, draw the projections of the skew lines AD and BE and show the projections of the shortest horizontal distance between them.
