Hey bro,
your answer-
We will draw a line passing through point C such that it is parallel to both EF and AB.Let the line be XY
Now considering CY॥ EF,CE is the transversal,
angleCEF+angleECY=180
(co-interior angles)
=>160+angle ECY=180=>angle ECY=20°
Now , considering CX॥AB,
47°+ angleBCX=180=>angle BCX=180-47=133°
Since,
AB॥CX or AB॥XY
and,AB॥CY or AB॥EF
.
.
.Thus,AB॥EF (since lines which are parallel to the same line are parallel to each other)
Thus proved.
