(((10+6)||64)+7.2)|| 30=(80+7.2) and 30 are in parallel, I can use current divider rule to find the current for 30 ohm resistor an calculate the voltage across it, but does not work.
Even I tried the mesh current, no luck ;(

but does not work
Show us you calculations so we can see how it "does not work".

60V,300W, 57.6w.
In the part of calculating 16|| 64, I was forgetting the numerator 1104/80, and just carrying on with 80 ohm, silly me!!!! I will fail this exam with this level of stupidity

I also got 60V. You know what you are doing. In the exam do the problems you know first and save the hard ones to last. Don't get stuck on one question.

Think positive. "I defiantly know I will fail" lol
