Step-by-step explanation:

<qpr+<prs=180°

50°+y=180° (sum of cointerior angles is 180°

and ab||CD with transversal pr)

y=130°

<rst+<rts+<str=180° (angle sum property of triangle)

rst=180°-110°=70°

rts=x

str=180°-130=50°

so, 70°+x+50°=180°

120°+x=180°

x=60°

x=60°

y=130°

y+x=130+60=190°

y-x=130-60=70°
