Question

Find x if a and b vector are parallel to each other. a vector=2i^-j^+3k^ and b vector=3i^+xj^+4k^​

Answer 1

Answer:

X= 12

Step-by-step explanation:

When two vectors are parallel to each other then their dot product will be zero

$(2i - j + 3k).(3i + xj + 4k) = 0 \\ 6 - x + 12 = 0 \\ x = 18$
