Answer:
15 units
Step-by-step explanation:
UW is the midsegment of ΔVXY,
By midsegment theorem of a triangle,
"Segment joining the midpoints of two sides of a triangle is parallel to the third side and measure of midsegment is half of the length of the third side."
UW = [tex]\frac{1}{2}(XY)[/tex]
Since, XY = 30 units
UW = [tex]\frac{1}{2}(30)[/tex]
= 15 units
Therefore, length of the midsegment UW = 15 units will be the answer.
