Who knows how to do this I TRULY NEED HELP

11

Step-by-step explanation:

if the two triangles are similar, that means that they are proportional to each other.

If you look at how they are shaped, they look the same, just one is smaller.

When you compare the two, you see that on triangle EFU, side EU corresponds with side VU on triangle VWU

EU = 7 and VU = 35

now divide so see what the multiplying factor is

35/7 = 5

so, when you divide the values on triangle VWU by 5, you get the values for  triangle EFU

35/5 = 7

side UW corresponds with side UF

UW = 55 and UF = ?

55/5 = 11

Side UF = 11
