plz solve...need some help​

Answer 1

Answer:

$given - ps \: is \: median \: \\ so \: as \: we \: know \: that \: sum \: of \: \\ any \: two \: sides \: is \: greater \: than \: third \: side \: so \: \\ pq \ + qs > ps - - - - - 1 \\ and \: pr + rs > ps - - - - 2 \\ \\ add \: 1 \: and 2\: we \: get \: (Pq + pr) > 2ps \\ hence \: proved$

Answer 2
