Question

In the given figure, ABCD is a parallelogram. Find the value of x, y and z​

Answer 1

Answer: =70  

∘

Step-by-step explanation:From the figure  

AD∥BC,BD is the transversal line  

⟹∠ADB=∠DBC     (∵alternate angles)

⟹z=30  

∘

 

Also

100  

∘

,x are supplementary angles  

So x=180  

∘

−100  

∘

=80  

∘

 

x,y,30  

∘

 forms a triangle  

⟹x+y+30  

∘

=180  

∘

 

⟹y=180  

∘

−80  

∘

−30  

∘

=70
