Hello again,
(10) $\displaystyle m \angle DCE=m \angle BDC=40$
Alternate interior angles are congruent.
$\displaystyle m \angle CDE=90$
$\displaystyle m \angle DBA=180-130=50$
$\displaystyle m \angle DBC=50$
Opposite angles of a parallelogram are congruent.

Corresponding angles are congruent: $\displaystyle 65=36+m \angle TVU$
$\displaystyle m \angle TVU=29$
$\displaystyle m \angle U=115$
Opposite angles of a parallelogram are congruent.
