**Can someone help me with 2 circuit problems...please!!!**

1. The equivalent resistance between points A and B of the resistors shown below is 38 ohms. Find the value of the resistance R.

The resistor looks like this

55 Ohms

_____\/\/\/\/_____

12 Ohms | |

A | |

.____/\/\/\__ | |______. B

R

I have no idea what to do...please help.

2. Determine the magnitudes and directions of the currents through R1 and R2, where R1 = 36 ohms and R2 = 10 ohms. I already found the directions. they are both from right to the left, I just need the magnitudes. The Bs represent batteries, and the + next to them indicates the positive side of the battery. I am also really lost on this one can anyone help?

V1=9.0V R1
