Answer 1

Answer

∠PQR+ext.∠Q=180  

∘

 [Linear pair]

∠PQR+80  

∘

=180  

∘

⇒∠PQR=100  

∘

 

       x+100  

∘

=180  

∘

 [Supplementary angles of parallelogram]

                       x=80  

∘

 

In △PSR, Z=∠SRP [Alternate angles]

∴80  

∘

+60  

∘

+Z=180  

∘

⇒Z=180  

∘

−140  

∘

=40  

∘

 

In △PQR,

∘

+y+100  

∘

=80  

∘

 

       y=180
