The given figure is a cross-section of a distorted C-channel. The distortion happened in such a way that its two sides are still parallel.
The angle ∠x is degrees.

Solution
The cross-section of the distorted C-channel with two parallel sides is as follows:
Here, the upward projected sides are parallel to each other, and the base is the transversal to the parallel sides.
∴ The shown ∠x and 110o are the pair of co-interior angles.
According to the co-interior angle theorem, ∠x+110o=180o ⇒∠x=180o−110o=70o
