Question

In the given figure, if AB || CD, ∠= 50° and ∠ = 130°, Then ∠ is: a) 130° b) 50° c) 80° d) 30°​

Answer 1

Step-by-step explanation:

angle APR= angle PRD

because they are alternate angles and alternate angles are are congruent.

APR =130°

from figure

APQ+QPR=130°

50°+ QPR=130

QPR= 80°

opt. C is correct

hope it's help you

Answer 2

Step-by-step explanation:

PQR is a triangle so angle sum property is 180. prq and prd are linear pair then 180-130=50,pqr Is 50 angle sum property is 50+50+x=180,100+x=180,x=180-100=80
