Answer:
XY = 92
Step-by-step explanation:
Midsegment theorem states that "a segment connecting midpoints of two sides of a triangle is parallel and half of the length of third side."
By this theorem,
XY = 2(UW)
z + 46 = 2z
z + 46 - z = 2z - z
z = 46
XY = z + 46
= 46 + 46
= 92
Therefore, length of XY = 92 is the answer.
