Final answer:
The length of Wx in the trapezoid is equal to the average of the lengths of TU and SV.
Step-by-step explanation:
Given that bar (SV) is the midsegment of the trapezoid TUWX, we can use the midsegment theorem to find WX. According to the midsegment theorem, the length of the midsegment is equal to the average of the lengths of the two bases of the trapezoid. Therefore, we can calculate WX by finding the average of TU and SV.
WX = (TU + SV) / 2
Substituting the given values, WX = (42 + 53) / 2 = 47.5
Therefore, Wx is equal to 47.5.
