The value of x is 40 degrees.
How to find angle when parallel lines are cut by a transversal?
When parallel lines are cut across by a transversal, angles relationships are formed such as corresponding angles, alternate angles, vertically opposite angles etc.
Therefore,
40° ≅ 40° (Vertically opposite angles)
Therefore,
40° ≅ 40°(corresponding angles)
Hence,
180 - 140 = 40(adjacent angles)
