Given the shown figure:

lines l and m are parallel

So, m∠A = m∠ABC

Because the alternative angles are congruent

So, m∠ABC = 108°

And BD bisects the m∠ABC

So, m∠CBD = 1/2 * m∠ABC = 1/2 * 108 = 54°

As the lines l and m are parallel

So, m∠CBD = m∠D = x

So, the answer will be x = 54

The answer will be A) 54
