Answer:

(D)

Step-by-step explanation:

It is given that Kite WXYZ has a short diagonal of XZ and a long diagonal of WY. The diagonals intersect at point V. The length of XZ = 8cm, and the measure of ∠XYV is 30°.

We know that the diagonals are the perpendicular bisectors of each other, therefore \(XZ=ZV+VX\)⇒\(ZV=VX=4 cm\).

Now, from ΔVXY using trigonometry, we get

\(\frac{XV}{VY}=tan30^{\circ}\)

Substituting the given values, we get

\(\frac{4}{VY}=\frac{1}{\sqrt{3}}\)

\(VY=4\sqrt{3} cm\)

Therefore, the length of the segment VY is \(4\sqrt{3} cm\).

Hence, option D is correct.
