Given the horizontal and vertical projections of two planes ABC and ADE.
A = 190 - 90 - 5
(a) Determine the line of intersection between the planes.
(b) Determine the dihedral angle between the planes.
(c) Show the projections of a horizontal line drawn from D, which is 40 mm long and is inclined at 60° to the line AD.
(d) On a separate diagram, draw the projections of the skew lines AC and DE and show the projections of the shortest distance between them.
