Friends I have a question i tried to solve but some cal not right kindly solve this question

A Earth station has receiving Antenna gain is 40 db,Noise temp =60K
Satellite transmitting gain 6db,prog loss=190db
Brf=1mhz
Lp=190db,teq=60
f2=10db,
snr=20db
g1=20db
felna teq=250

Calculate Average Noise power at the Receiver output.2)Min Satellite TRansmitted power aceuve 20db,Snr at receiver output.
