Hello, I am new to AAC forums and I have a question on one of the problems form my textbook. I have tried various methods to obtain the resistance of the unknown variable but have no luck so far. There was also a hint that suggested to find the current in the 25Ω first, but how? Current divider?
Any tips on how to start this?
The picture of the circuit is below.
Things I have tried
KCL, KCV, Ohms Law
Here are the equations that I have (un)successfully tried to use, but there seems to be too many variables.
Assuming the first node (v1) is above the 50Ω and the second node (v2) is above the 25Ω.

Rich (BB code):
V=IR
Known
I(total) = 8A
R1=50Ω
R2=Ro
R3=25Ω
V(Ro)=240V
KCL
node1: I(source)  V1/50Ω  (V1V2)/Ro = 0
node2: V2V1/Ro  V2/25Ω = 0
KVL
Mesh 1 on left and Mesh 2 on right
Mesh 1 = 50Ω(8AI2)
Mesh 2 = 25Ω(I2) + 50Ω(I2I1) + 240V
