Given the horizontal and vertical projections of two planes ABC and ADE.
A = 290 - 5 - 140
(a) Determine the line of intersection between the planes.
(b) Determine the dihedral angle between the planes.
(c) Show the projections of a straight line drawn from B to the line DE and which shall be 85 mm long.
(d) On a separate diagram, draw the projections of the skew lines AD and BC and show the projections of the shortest horizontal distance between them.
