Find the theacutevenin equivalent circuit for that portion

Question

For the transistor network of given figure:

a. Find the Thévenin equivalent circuit for that portion of the network to the left of the base (B) terminal.

b. Using the fact that I_C = I_E and V_CE = 8 V, determine the magnitude of I_E.

c. Using the results of parts (a) and (b), calculate the base current IB if V_BE = 0.7 V.

d. What is the voltage V_C?
