Can someone do 19 please

In Problems 17-22, find symmetric equations of the line containing the point Po. 17. Po = (4, 2, 1) and the line is in the direction of the vector D = 2i + k. 18. Po - (-1, 2, 0) and the line is in the direction of the vector D - 2k - j. 19. Po = (0, 0, 0) and the line is perpendicular to each of the lines and 2 3 1 3 1 2+1 3 2 20. Po = (0. 0, 0) and the line is perpendicular to each of the lines I + 2 z + 1 and 4 2 z. 5 3 21. Po = (1, 2, -1) and the line is perpendicular ly the vectors u - 21 + 4j - 2k and v - -31 - 2j + k. 22. Po = (-1, 3, 2) and the line is perpendicular to the vectors u - -21 + 2j - 3k and v - 4i + 2j + k. In Problems 23-30
