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

A = 285 - 50 - 85
B = 260 - 95 - 15
C= 210 - 25 - 35
D= 255 - 10 - 95
E= 205 - 80 - 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.
