The #"C-C-C"# bond angles in a planar cyclohexane would be 120 °.

Explanation:

A planar cyclohexane would look like a regular hexagon.

It has six sides and six interior angles

A theorem from geometry states that, for a regular polygon,

#"Sum of interior angles" = (n-2) × 180°#, where #n# is the number of interior angles.

#"Each interior angle" = (n-2)/n × 180 °= (6-2)/6 × 180 ° = 4/6 × 180 ° = 120 °#.

Each #"C-C-C"# bond angle in a planar cyclohexane would be 120 °.
