Answer:
y = 7
Step-by-step explanation:
The similarity statement
tells you which vertex from the first polygon corresponds to which vertex from the second polygon.
A is paired with W, B is paired with X, C is paired with Y, D is paired with Z.
The expression <em>y</em> + 2 is placed along side WZ which corresponds to side AD in the first polygon.
Now locate two sides, one from each polygon, that are labeled with just <u>numbers</u>. That way, you'll be able to tell what the proportion is between the two shapes.
AB and WX correspond and are labeled 5 and 3, respectively.
Now you can write a proportion:

Use the Means-Extremes Property ("cross multiply").

8x-9y=11
First you move the 8x because you have to leave the 9y alone
8x-9y=11
-8x -8x
-9y=11-8x
Now you have to move the -9, so the inverse of multiplying is dividing so you divide -9.
-9y/-9= 11/-9 -8x/-9
since you can't have negative as a denominator it would be:
y= -11/9+8x/9
