The answer is: " x = 91 " .
____________________________________________
Note: "x + 32 = 123 " ;
{since: 1) the "123° angle" shown in the diagram ; AND:
2) the angle formed by the 2 (two) angles:
" ∠x" and the "32° angles (shown in the diagram) } ;
____________________________________________________
→ are "altenrate interior angles";
and "alternate interior angles" are congruent.
____________________________________________________
So, x = 123 - 32 = 91 .

The answer is: " x = 91 " .
