A 1,2-cis disubstituted cyclohexane will have one axial and one equatorial atom.

Work Step by Step

To be cis means that both atoms must point in the same direction. Since the molecule is a 1,2 cis it means that we are looking at adjacent atoms. The axial atoms in a chair cyclohexane always alternates in where it points. Thus there must be one axial and one equatorial in order to point in the same direction.
