i need help proving it with postulates

How about this, assuming your using 2 column proofs: 
m<QST=m<RSP   - Given
m<QST = m < QSP + m < PST - angle addition pos. 
m<RSP = m < RSQ + m < QSP 
m < RSQ + m < QSP = m < QSP + m < PST  - substitution property (could be 2 steps)
m <RSQ = m<PST  - subtraction prop equality
<RSQ cong. <PST  - def. congruence
