Question

the given figure AB||CD angle A PQ =50 degree, and angle PRD=130°, then QPR is ​

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

so angleQPR makes 180 degree

Step-by-step explanation:

Answer 2

Answer:

Step-by-step explanation:

We know that, ∠APR = ∠PRD … [because interior alternate angles]

∠APQ + ∠QPR = 130

50 + ∠QPR = 130

∠QPR = 130 – 50

Hence, ∠QPR = 80
