Answer:

x = 3

Explanation:


\triangle TFG\sim \triangle TUV... (given)


\therefore (FG)/(UV)=(TG)/(TV) ... (csst)


\therefore (45)/(63)=(10x+5)/(49)


\therefore (5)/(7)=(10x+5)/(49)


\therefore 10x+5= (5* 49)/(7)


\therefore 10x+5=5* 7


\therefore 10x+5=35


\therefore 10x=35-5


\therefore 10x=30


\therefore x=(30)/(10)


\therefore x=3
