Step-by-step explanation:
Using ∆ law of vector addition,
PR→=PQ→+QR→PR→=PQ→+QR→ - (i)
Also,
RP→=RS→+SP→RP→=RS→+SP→ - (ii)
Taking LHS,
=PQ→+QR→+RS→+SP→=PQ→+QR→+RS→+SP→
[Put value of PR→=PQ→+QR→PR→=PQ→+QR→ from equation (i) ]
=(PR→)+RS→+SP→=(PR→)+RS→+SP→
[Put value of RP→=RS→+SP→RP→=RS→+SP→ from equation (ii) ]
=PR→+RP→=PR→+RP→
=PR→−PR→=PR→−PR→
=0=0

Perimeter of a triangle = all 3 sides added together
x + (x - 4) + (x - 4) = 19
3x - 8 = 19
3x = 19 + 8
3x = 27
x = 27/3
x = 9 <==
