Answer 1

Answer:

draw a line x y parallel to ST AND PQ.

Step-by-step explanation:

NOW, ∠PQR+∠QRX=180° (CO- INTIRIOR ANGLES)

110+∠QRX=180

∠QRX=70      .....(1)

SIMILARLY,

∠TSR+SRY=180

∠SRY=50   ....(2)

NOW,

∠SRY+∠QRX+∠QRS=180°     (STRAIGHT LINE)

50+70+∠QRS=180

∠QRS= 60°

HENCE YOUR ANSWER IS 60°
