1. The problem statement, all variables and given/known data
I need to find to resistance and am having problem as I do not know KCL's. All I know is the total resistance in series or parallel. I have attached the image. Find resistance b/w the 2 ends. 2. Relevant equations If you have Resnik & Halliday open page 723(Vol2). and see figure 3141. My question is same with r = 20ohm & R=10ohm. 3. The attempt at a solution

One resistor has zero current inside due to symmetry, you can remove it and use your formulas for resistors in series/parallel afterwards.
