Answer:

PY=\frac{16}{3}

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

\frac{PX}{PQ}=\frac{PY}{PR}

Substituting the given values, we have

\frac{4}{10}=\frac{PY}{PY+8}

\frac{2}{5}=\frac{PY}{PY+8}

2PY+16=5PY

16=3PY

PY=\frac{16}{3}

Thus, the value of PY is {\frac{16}{3}.
