The vectors are equal in length and pair wise make equal angles. If , then
The given vectors are .
All the three vectors are of equal lengths.
...(1)
So, the length of all the vectors will be √2
Let the angle between each pair from the given vectors be A.
Let's write the dot product of each pair.
The next pair will be
Now we will solve the equation
y + z = 1 ...(3)
x + y = 1 ...(4)
Subtracting (4) from (3)
z  x = 0
x = z
Now, we know that length of all vectors is √2
We will rearrange equation (3) and substitute in the above equation.
y + z = 1
y = 1  z
If we see the options, we don't have the value of z component as fraction. So, we will just focus on the value of z = 1
y = 1  z
y = 1  1
y = 0
x + y = 1
x + 0 = 1
x = 1
The solution is (1,0,1).
