I see that you have already looked at the solutions to a very similar problem below. Follow the recipes laid out by Reiny and Steve and you should get it.
QR=8, RS=16, UV=18, VT=34,M<S=36, M<T=36
A. No, the triangles are not similar.
B. Yes, the scale factor is 1:2.
C. Yes, the scale factor is 4:9.
D. Yes, the scale factor is 8:17.
