Solution

The correct option is C

90x2



At point A
Here,x+BAD=180 (linear pair)BAD=(180x) As ABCD is a parallelogram, then BAD=BCD=(180x)
Intersection of two pair of parallel lines forms a parallelogram and opposite angles are equal in a parallelogram

Also, ECF=y+y=2y(2y)=ECF=BC=(180x) [Vertically Opposite angles]y=(180x)2y=90(x2)
