Answer:
Step-by-step explanation:
It is given that PQR is a triangle and X and Y are the points on the sides PQ and PR respectively, and PX=4cm, XQ=6cm and YR=8cm.
Since, XY is parallel to QR, thus the triangle PXY is similar to triangle PQR, hence using the basic proportionality theorem, we get
Substituting the given values, we have
Thus, the value of PY is .
