hi guys, ive been going through my past exam papers and i found this question. my lecturer says that a similar question will be on my exam but i havent got any idea how to do it

i have to determine the current through RL, the voltage across RL and the power developed in RL for the following values of RL using thevenins theorem.

(i) RL = 1 ohm

(ii) RL = 2.83 ohm

(iii) RL = 4 ohm

Im so confused!!!!
