Question

wxyz is a trapezoid. if $overline{xz}=8.5$, what must be the value of $overline{wy}$ for wxyz to be an isosceles trapezoid? (1 point) 4.25 17 34 8.5

Explanation:

Step1: Recall isosceles trapezoid property

In an isosceles trapezoid, the diagonals are equal.

Step2: Identify diagonals

The diagonals of trapezoid $WXYZ$ are $\overline{XZ}$ and $\overline{WY}$.

Step3: Determine length of $\overline{WY}$

Since $\overline{XZ}=8.5$ and diagonals of isosceles trapezoid are equal, $\overline{WY}=\overline{XZ} = 8.5$.

Answer:

8.5
