I assume you want to know each side length ???

 

If I'm seeing this correctly,   we have

 

[3x + 4]  + [2x + 3]  +  [ 2x  - 9  ]   =  75   simplify

 

7x  - 2  =  75      add 2 to both sides

 

7x   =  77            divide by 7

 

x  =  11

 

So,  one side  =   3(11) + 4   =   37

One side = 2(11) + 3  =  25

And one side  = 2(11) - 9  =  13
