This is a pic of the BJT.

For the amplifier circuit above, find a) RB and b) the gain (∆Vout/∆Vin) such that Vout = 8.3 V . Assume β = 155, RC = 8.6 kOhm, RE = 0.5 kOhm, VCC = 10 V, VBB = 1.02 V and VBE = 0.7 V.
I need to find the value of resistor Rb and the gain. For Rb, I thought I could just find the currents through Re and Rc and then use KCL to find the current through Rb. Then I could use that to find Rb but no luck.
Can someone help?
