Question

PQ//RS EF//QS ANGLE PQS IS 60 FIND ANGLE RFE WITH STEPS

Answer 1

Answer:

we can find this answer by pqs =rfe so , 180 - 60 = 120 rfe =120

Answer 2

Answer:

PQ//RS and EF//QS

Angle PQS =60°

angle PQS = angle EFS ............(1)

60° = 60°

and angle RFE = angle FSQ .............(2)

angle RFE + angle RFE....[From (2)]....(3)

= 2*angle RFE

Because angle PQS + angle RFE + angle EFS+ angle FSQ =360

60°+ angle RFE +60°+ angle FSQ =360°

120° + 2*angle RFE =360°

2*angle RFE = 360°-120°

2*angle RFE =240°

angle RFE =240°/2

angle RFE = 120°
