QT is 11.

here's how it works out.

you are given that:

QS is 7 and RT is 6 and RS is 2.

since RS is 2, then QR is 5 and ST is 4.

going from left to right, you get:

QR is 5, RS is 2, ST is 4.

add them up and you get 11.

my diagram shows the breakdown.



     Q----------------R---------------S--------------T
              5               2               4

                      R---------------S
                              2
 
     Q--------------------------------S
                     7


                     R--------------------------------T
                                      6

QR is 7 - 2 = 5
ST is 6 - 2 = 4
