there is a formula for vectors
cos²a+cos²b+cos²c=1
where a,b and c are angles made by the vector with the x,y and z axes respectively.
a=b=c
3cos²a=1
cos²a=1/3
cos a=1/√3
A=1/√3×(i+j+k)
cos²a+cos²b+cos²c=1
where a,b and c are angles made by the vector with the x,y and z axes respectively.
a=b=c
3cos²a=1

Answer:
Solution:
The given system has different sets of axes with which vector A makes equal angle accordingly, so the component will formed in respect to vector A, which can be given by,
Given data suggest that, angle a with x axis = angle b with y axis = angle c with z axis
Thereby, as we know that there is an equation derived for the component for vector which makes angle in 3 dimensions, which is,
As, a = b = c
