Question

If you solve this please show me how, no other information is on it? Tank you. its x =? I guess

Answer 1

By similarity theorem,

`\begin{gathered} (TV)/(TS)=(UV)/(SR) \\ \text{but let SV=y} \\ (6)/(6+y)=(4)/(12) \\ \text{cross multiply to get} \\ 4(6+y)=6*12 \\ 24+4y=72_{} \\ 4y=72-24 \\ 4y=48 \\ y=(48)/(4) \\ y=12 \\ So,\text{ X=SV+VT} \\ X=12+6 \\ X=18 \end{gathered}`

The value of X is 18.
