1. The problem statement, all variables and given/known data A line has direction angles 60°, 45°, 60° and passes through the point (1, -2, 5). Determine the vector equation of this line. 2. Relevant equations I honestly have no clue. My teacher gave a hint it has to do with trig (as in the trig ratios) and the unit vector formula, but I don't see how they mix. 3. The attempt at a solution Tried everything except the right way for the last week, resulting in dead ends.
