Verified Answer
In the given figure, PQ||RS and EF||QS. If ∠PQS = 60°, then...
60°+ QSR=180°[co interior angles]
QSR=120°
RFE=QSR
So,RFE=120°

In the given figure, PQ||RS and EF||QS. If ∠PQS = 60°, then...
In the given figure, PQ || RS and EF || QS.
Given - PQ || RS and EF || QS, angle PQS is = 60 degree 
To Find - Angle RFE 
Solution - 
            60 + angle FSQ = 180 ( Co interior angles) 
Angle FSQ = 120 degrees 

           Angle QSF + Angle EFS = 180 (CO Interior angles) 
           Angle EFS = 60 degrees 
          Angle EFS + RFE = 180 (Linear Pair) 
          Angle RFE = 180 - 60 
So angle RFE = 120 degrees 

option (b) is correct
