QR is the transversal
Angle 1+110=180 angle 1=70
In same methid SR is the transversal
Angle 2=50
XRY is a straight line
Angle 1+angle 2 +x=180
70+50+X=180
X=60

@pushpendravikramsingh3928

angle SRB = 50°
PQ||ST
ST||AB
:: AB||PQ
PQR=QRS
QRB=QRB+SRB
QRS=QRB-SRB
QRS=110°-50°
QRS= 60°

@Ankiteast

Right Answer is the 60

@kiraxd581

Construction : draw a line parallel to pq an that touch R

@vishalgaikwad4331

This question is very for IIT Students like me answer is (x=60)

a=180°–110°

a=70=ans
