Figure T is similar to figure W which answer is closest to the length of side XY
beks73 [17]
As they are similar triangles, one is simply going to be bigger than the other, meaning that if triangle T’s side QS is = 9 and triangle W’s corresponding side ZX is =6.5. When dividing 9 by 6.5, it is obvious that triangle W is 0.72 smaller than triangle T. All you then have to do to calculate length of side XY is times side QR on triangle T -cause it’s the corresponding side of these two triangles- by 0.72, and you’ll have your answer of XY= 8.125 :)
