boss here is ur answer either u can use this method or can prove triangle str and sqr congruent by sas test and then angle tsr and srq will be equal by cact then st and qr are parallel by alternate angles theorem then angle pst equal to pqr by corresponding angles theorem hence pst is 65 this method is also comfortable or u can also follow first no issue
