Answer:
XY = 9
Step-by-step explanation:
STEP 1: Set up a proportion
[tex] \frac{xy}{12} = \frac{6}{8} [/tex]
(I created this based on "Quad ABCD ~ Quad WXYZ" because it revealed to me which sides are related)
STEP 2: Cross multiply
8(XY)=72
STEP 3: Divide
XY = 9
CHECK:
(The fractions must be equivalent)
[tex] \frac{9}{12} = \frac{6}{8} [/tex]
0.75 = 0.75
Hope this helped ^^
