Answer:

Option (D). 5

Step-by-step explanation:

From the given figure,

In a ΔWXY,

XR ≅ RY and QY ≅ QW

That means QR is the mid-segment.

By the theorem of mid-segments,

[tex]QR=\frac{1}{2}(XW)[/tex]

(2x - 3) = [tex]\frac{1}{2}(x+9)[/tex]

2(2x - 3) = x + 9

4x - 6 = x + 9

(4x - 6) + 6 = (x + 9) + 6

4x = x + 15

4x - x = (x + 15) - x

3x = 15

x = [tex]\frac{15}{3}[/tex]

x = 5

Therefore, Option (D) will be the answer.
