Answer:
XY = 4 units
Step-by-step explanation:
We are given a figure of a bigger triangle PQR with a smaller triangle PXY within it. The length of the line QR is units and we are to determine the length of the mid segment XY.
SInce the side lengths of these triangles are proportional and XY is the mid-segment, then its length would be half of QR.
XY = [tex]\frac{1}{2}[/tex] QR
XY = [tex]\frac{1}{2} * 8[/tex]
XY = 4 units
