Answer:
PR = 28
Step-by-step explanation:
Since PQRS is a rectangle, the diagonals PR and QS should have the same length. Therefore it holds:
[tex]9 x + 1 = 13 x - 11 \iff (13 - 9) x = 1 + 11 \iff x = \frac{12}{4} = 3[/tex]
So, [tex]PR = QS = 9 \cdot 3 + 1 = 28[/tex].
You meant PR, right? I don’t know what “tr” is.
