Question

In the figure given above PU is parallel to SR, PR is parallel to SV. find a, b.

pls answer the question quickly with proper explanation. pls​​

Answer 1

Answer:As TU∥SR and TR is the transversal line

∠TRS+∠RTU=180  

∘

 

⟹∠TRS=90  

∘

 

∠PRS=∠TRS=90  

∘

   (∵vertically opposite angles)

In △PQR,

∠P+∠Q+∠R=180  

∘

 

⟹50  

∘

+b+90  

∘

=180  

∘

 

⟹b=40  

∘
