angle Y = 80°( Alternate Interior Angles)
Angle STR + Angle SRT = 180 -110
2×Angle SRT = 70° ( Reason Angle STR = Angle SRT...issoceles ∆)
Angle SRT = 70/2 = 35°
Angle S + Angle SRT = Angle UTR ( Exterior angle property of ∆)
= 110 + 35 = angle X + angle PTR (Angle UTR = Angle X + Angle PTR)
= > 145 = Angle X + 90° (Angle PTR = Angle P... corresponding angle)
=> Angle X = 55°
X + Y = 135°
