1.	position vectors of A,B relative to origin are a,b the side BC,CA,AB of a triangle ABC are cut by a line at X,Y,Z show that AZ/ZB×BX/XC×CY/YA =-1
Answer» ANSWER: If X is the position vector of B, then a DIVIDES AB in the RATION 42:3 ∴a=2+32x+3(a+2b) ⇒5a−3a−6b=2x⇒x=a−3b

Answer»

ANSWER:

If X is the position vector of B, then a DIVIDES AB in the RATION 42:3

∴a=2+32x+3(a+2b)

⇒5a−3a−6b=2x⇒x=a−3b
