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 °.
