From the question;
Point A is at (2,2)
Point B is the reflection of point A across the x-axis;
The rule for reflection across the x-axis is;

So, point B will be;

The point C is 5 units directly left of point B;
So, point C will be;

Therefore, the coordinates of the Points A, B and C are;

Shown as;
So, the length AB is;

The length BC is;
