A line with positive direction cosines passes through the point P (2,1,2) and makes equal angles with the coordinate axes. The line meets the plane at point Q. The length of the line segment PQ equals units.
Answer: (C)
Solution
Equal angles with the axes and positive direction cosines mean , so points on the line are where . For the printed plane this gives , so , which is not among the
