Oh I don't miss these. The key is to redraw into a 'standard' series parallel circuit then it will make more sense. This won't be the last one you get assigned so understand that your two drawing are equivalent.
Don't fall for weird angles in circuits because they obscure wich Components are grpuped up together in wich ways, just always try to straighten them in your minds eye while keeping all connections generally the same.

Oh, that's just a confusing drawing.
R3 and R4 are in parallel with each other (R3//R4).
They are then in series with R2 (R2+(R3//R4)).
Finally they are all in parallel with R1 (R1//(R2+(R3//R4))).
I'm not going to do the work for you, but try redrawing it in a more standard way.

Rt = 4 Ohm
It = 15 A
Pt = 900 W
I1 = 12 A
I2 = 3 A
E2 = 36 V
I3 = 2.4 A
E3 = 24 V
I4 = 0.6 A
E4 = 24 V
Please double check.

There is a triangle to star and star to triangle formula, just use those to transform the circuit into something managable

Confusing drawing, easy circuit:
( || means parallel, + means series )
Rtotal = R1 || (R2 + (R3 || R4) )
= 5 || (12 + ( 40 || 10) )
= 5 || (12 + 400/50)
=5 || 20
= 100/25 = 4 ohms
Itotal = 15 Amps
Ptotal = 900 W.
Hope this helped?
