Given the horizontal and vertical projections of two planes ABCD and ABE.
A = 285 - 50 - 85
(a) Determine the dihedral angle between the planes.
(b) Determine the position of a point P on the plane ABCD which shall be at a distance of 35mm from the horizontal plane and 75 mm from the vertical plane Join EP and determine the inclination of EP to the plane ABCD.
(c) On a separate diagram, draw the projections of the skew lines AE and BC and show the projections of the shortest horizontal distance between them.
