Given the horizontal and vertical protections of two planes ABCD and ABE.

A = 145 - 55 - 5
B = 185 - 15 - 85
C = 225 - 50 - 90
D = 205 - 80 - 40
E = 130 - 100 - 45

(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.
