Question

In the given figure, AB || CD and angle APQ = 70° and angle PRD = 130” Find the value of z and y .
​

Answer 1

Answer:

AB || CD,

∠ APQ = 50°

∠PRD = 130°

in figure QP joins AB at P

and if we extend it

vertically opposite angles are equal

∠PRD is intersect CD line

Angle BPR +angle PRD = 50+130=180

so , it is a property of parallel and trsnsversal line property

thats why ,theQPR is straight line
