The correct answer is ;
QR=9
QP=6
TU=19
TS=?
Okay so the triangles are kindred, now the equation can be made
9/16=6/x
So now we are going to cross multiply
9x=114
Now divide both sides by
912 2/3
Your answer is:
TS=12.6 the correct answer is D.12.7

Hope this helps u

Set up a proportion since the two triangles are proportional.

QP/TS= QR/TU
6/TS= 9/19
cross multiply
(6*19)= (9*TS)
114= 9TS
divide both sides by 9
12.666666= TS
round up to the tenths decimal place
12.7= TS

ANSWER: D) 12.7 is TS

Hope this helps! :)
