Hello, Proclivitas!
$\displaystyle \begin{array}{cccccc}1. & \angle B = \angle D && 1. & \text{Given} \\ 2. & \angle BXA = \angle DXC && 2. & \text{Vertical angles} \\ 3. & \Delta BXA \sim \Delta DXC && 3. & a.a.a. \\ 4. & \frac{BX}{BA} = \frac{DX}{DC} && 4. & \text{Proportions} \\ 5. & BX\cdot DC = BA\cdot DX && 5. & \text{Muliply by }BA\cdot DC \end{array}$
