So,

Look at all three denominators.

Factor them completely.

Putting them together, we would get the following:
I need to see the tape diagram and the full problem.
If sides are congruent then the angles ACROSS from them are also congruent.
Since WV and VU are congruent, angle U is congruent to angle W.
Set up an equation and solve.
See attachment.
x = 8
Angle w = 63
5/6 is smaller than 6/6 cause 6/6 is =1 5/6 is smaller than 1 whole
