I need help with a conventional resistive circuit , I can do the thevenin calculation but I can't come up with the voltage drop on the load resistor that they did when I do it the conventional way and that is 19.1

 

Is the question related with your job or it just your personal pratice?

Your question just like the homework, and the helpers can't do the homework for you, because it may get ban from this forum, they only can do is the guidance.

 

Consider the step that got you to 44V for V Thevenin. You used the voltage divider rule. Just do it again with Rth and the load resistor. The load resistor acts like any other resistor divider network.
