Geometry homework is due today help me, please

Remember that opposite angles in a parallelogram are equal

So  angle R  =  67°

And consecutive angles are supplementary

So

angle   QTS  + angle QST + angle RSQ   = 180

       67          +      63        +   angle RSQ   = 180

                   130                +  angle RSQ  =  180

                                            angle RSQ  =  180 - 130  = 50 °

And opposite sides are equal....so...

4x  =16

x  = 4
