Question

in the following figure ROSE is a parallelogram find the value of x,yand z ​

Answer 1

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∘

Answer 2

Answer:

y = 70

and z = 80

and z =30

hope it help
