The Si transistor of Fig 3-19 has It}: 51] and negligible leakage current. Let Vac = 13?

Please here is the questions. Could you kindly help me out.

The Si transistor of Fig 3-19 has It}: 51] and negligible leakage current. Let Vac = 13?,V55 = 4V. R5 = 2110 $2, and RC = 41552. (:1) Find R3 so that 1.39 = 2mA. (3)) Determine thevalue of Vcag for V3 of part (a).
