Answer:
x=80°
y=60°
z=40°
Step-by-step explanation:
Sum of angles in a triangle = 180°
In ∆PQR
80° + 40° + y = 180°
=> 120° + y = 180°
=> y = 180° - 120°
=> y = 60°
As lines AB and CD are parallel and lines PQ and PR intersects the parallel lines then their interior angles will be equal.
That means
Angle PQR and Angle QPA are equal
=> x = 80°
Also Angle PRQ and Angle RPB are equal
=> z = 40°
