Hey everyone!

I can't seem to solve these two questions. Any help is appreciated!

1) A line has direction angles of 60 degrees, 45 degrees and 60 degrees. It passes through the point (1, -2, 5). Determine the vector equation of this line.

2) Find the vector equation of a line that intersects the following 2 lines at 90 degrees.

Line 1: (x,y,z) = (4, 8, -1) + a(2, 3, -4)

Line 2: (x, y,z) = (7, 2, -1) + a(6, 1, 2)

Thanks in advance
