Here is the answer✨✨✨✨✨✨✨
_______________________________
ATQ
PQ=10cm,QR=8cm,PR=12cm....
so, let we take PL=X
so, by angle sum property......
X+(10-X)+(10-X)+(12-X)+(12-X)+X=10+8+12
X+10-X+10-X+12-X+12-X+X=30
10+10+12+12-X-X=30
44-2X=30
-2X=30-44
-2X=-14
X=7
So, PL=7cm QM =3cm and RN=5cm.......
Hope it may help you ✨✨✨✨✨✨✨✨
