You add the vectors. I recommend break each of the distances into N and E vectors, so adding the four vectors can be done in components. I will be happy to critique your thinking or work.

Maths-Vectors Help!
Please can you help me as I have just been introduced to your Help Forum: Determine whether the vectors u, v and w given below are linearly independent or dependent where u, v and w are non-colliner vectors such that u=2a-3b+c , v=3a-5b+2c and w=4a-5b+c. thanks. Use exactly ...

You seem to have omitted the unit vector designation (usually written i, j and k). What you have written are not vectors, but sums of numbers. What does the equals sign in front of each trio of numbers represent? One doesn't take cross products of three vectors.
