    Hi. How would I find the emitter current of the bottom transistor in this circuit? I understand how to find the ie of a transistor in a circuit with only one tranistor by using this Ie*(Re/Rb + Re/Rc + 1) = Vcc(1/Rb + 1/Rc) - (Vbe/Rb + Vce/Rc)
    . My problem is that I cannot figure out the Rc of the bottom resistor.
