How to use mesh current analysis instead of thevenin's theorem here to solve for all currents and voltages in the following bjt circuit?

How should i make the closed loops in order to analyse?

...solve for all currents and voltages in the following bjt circuit?

A good place to start is to replace the BJT with the circuit model of a BJT.

I tried to find base current by applying kvl in the marked part of the circuit.



Can i use I2 as the base current?

 

hi D,
This simulation should give you a clue that a parameter is missing from the posted question.

Which parameter? beta?

 

Hi D,
The current in R3 [Emitter] will be higher than you calculated, due to the gain factor of the transistor.
Do you have a copy of the complete question you could post?

example 4 in this link here.
They used thevenin's theorem, i was just trying to find it through mesh analysis.The answer they get for emitter current is 1.29 mA while what i get through mesh analysis is 1.4 mA .
