The document contains descriptions of two lines with given dimensions and positions in space. It asks to draw the projections of the lines onto the horizontal and vertical planes and find the true inclinations of the lines relative to these planes. For the first line, it is 80 mm long with one end 10 mm above and 15 mm in front of the reference planes. The second line is 85 mm long with one end 25 mm above and 20 mm in front of the planes, and its projections onto the planes have given lengths.
