1.9 Vectors

Question 12

The points $A$ , $B\,$ and $C\,$ have position vectors $a=i+2j\mathbf{a} = \mathbf{i} + 2\mathbf{j}$ , $b=5i+4j\mathbf{b} = 5\mathbf{i} + 4\mathbf{j}$ and $c=3i+8j\mathbf{c} = 3\mathbf{i} + 8\mathbf{j}$

Find $∣AB⃗∣\left|\vec{AB}\right|$ and $∣BC⃗∣\left|\vec{BC}\right|$ , giving your answers as surds in their simplest form.
