Question

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

Answer 1

you need power

by training

Answer 2

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∘
