Angle between vectors ` veca and vecb " where " veca,vecb and vecc` are unit vectors satisfying ` veca + vecb + sqrt3 vecc = vec0` is

if veca , vecb ,vecc are three vectors such that veca +vecb + vecc = vec0 then

if veca , vecb ,vecc are three vectors such that veca +vecb + vecc = vec0 then

If veca, vecb, vecc are vectors such that veca.vecb=0 and veca + vecb = vecc then:

If veca, vecb, vecc are vectors such that veca.vecb=0 and veca + vecb = vecc then:

If veca,vecb and vecc are unit vectors such that veca+vecb+vecc=vec0 then angle between veca and vecb is

If veca,vecb and vecc are three unit vectors satisfying veca-vecb-sqrt3 vecc=0 then the angle between veca and vecc is:

If (veca xx vecb) xx vecc = vec a xx (vecb xx vecc) , where veca, vecb and vecc are any three vectors such that veca.vecb ne 0, vecb.vecc ne 0 , then veca and vecc are:

Three vectors veca,vecb and vecc satisfy the relation veca.vecb=0 and veca.vecc=0 . The vector veca is parallel to
