What is the measurements of QTR? Please show all work on how you got your answer

Answer:
The answer to your question is ∠QTR = 56°
Step-by-step explanation:
We know that QRST is a rectangle then
QT ║ RS and QR ║ TS
also, we know that the interior angles of a rectangle measure 90°.
That means that ∠QTR + ∠PTS = 90 because are complementary.
Then
∠QTR + 34° = 90°
∠QTR = 90 - 34
∠QTR = 56°
