Step-by-step explanation:
In the given figure,AB∥CD,CD\parallel EFandy:z=3:7$$
Let y=3a and z=7a
∠DHI=y(vertically opposite angles)
∠DHI+∠FIH=180 (Interior angles on the same side of the transversal)
⇒y+z=180
⇒3a+7a=180
⇒10a=180
or a=18
∴y=3×18
=54
and z=7×18
=126
∘
Also,x+y=180
∘
⇒x+54
∘
=180
∘
∴x=180
∘
−54
∘
=126
∘
Hence,x=126
