Question

In triangle PQR,,xy is parallel to qr, pq/xq=7/3 and pr=6.3cm find yr.

Answer 1

In the triangle PQR, as  XY || QR,
we have that    PQ/XQ = PR/YR  

         so YR = PR /  (PQ/XQ)   = 6.23 cm / (7/3) = 2.67 cm

Answer 2

Answer:

2.3cm

Step-by-step explanation:

px=pq-xq

px=7-3

px=4cm=py

py=4cm

yr=pr-py=6.3-4cm=2.3cm
