ANSWER
[tex]BC=12[/tex]EXPLANATION
First, let us make a sketch of the three points:
As we can see, AC is made up of AB and BC.
This means that the length of AC is the sum of the lengths of AB and BC.
That is:
[tex]\begin{gathered} AC=AB+BC \\ \Rightarrow BC=AC-AB \\ BC=22-10 \\ BC=12 \end{gathered}[/tex]The value of BC is 12.
