Answer:

8.4

Step-by-step explanation:

The diagonals of a rectangle are equal.

That means WY = XZ

16x+2 = 36x-6

Subtract 16x from each side.

16x -16x+2 = 36x-16x-6

2 = 20x -6

Add 6 to each side

2+6 = 20x-6+6

8 = 20x

Divide by 20

8/20 = 20x/20

2/5 =x

We want to find the length of the diagonal

WY = 16 ( 2/5) +2

Changing to decimal form

WY =16 * .4 +2

WY =6.4+2

     = 8.4
