do you know HOW to answer the question?

welshfella · Answer

the side ST in STUV corresponds to the WX in WXYZ
and they are in the ratio 3:1

bloomlocke367 · Answer

really, all you have to do is divide 117 by 3$$\frac{ 3 }{ 1 }=\frac{ 117 }{ ? }$$

bloomlocke367 · Answer

Cross multiply and divide and you'll have your answer! let me know what you get! :)
