Since EFparallelCDparallelAB
The sum of co-interior angle is 180degreei.e.
AngleE+AngleECD=180degree
130degree+angleECD=180
angleECD=180-130
angleECD=50(x)
Now CDparallelAB
The sum of co-interior angle is 180degreei.e.
AngleA+AngleDCA=180degree
140degree+angleDCA=180
angleDCA=180-140degree
angleDCA=40degree(y)
Now,AngleDCA+angleECD=angleECA
40degree+50degree=angleECA
90degree=angleECA
Hope you have understood....
