Question

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.

Answer 1

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.

$\therefore$ The shown $\angle x$ and ${110}^o$ are the pair of co-interior angles.

According to the co-interior angle theorem,
$\angle x+{110}^o={180}^o$
$\Rightarrow \angle x={180}^o-{110}^o={70}^o$
