Parallelograms. Can someone please help

QT = 5

Step-by-step explanation:

The diagonals on any parallelogram always bisect each other - cut each other in half. The two diagonals on URTS are RT and US. US cuts RT into two equal segments, RQ and QT, each of which is half of RT. So QT must be half of RT, and since RT = 10, QT = 5.

angle uzt is congruent to angle tzy. angle vzw is congruent to angle yzx.
