a) For the molecule shown in the above figure assure yourself that you can determine the hybridization and geometry of the carbon atom in the C=C bond. What is the approximate bond angle of this carbon atom ?
I tried 120, 180

b)For the molecule shown in the above figure assure yourself that you can determine the hybridization and geometry of the carbon atom in the CN triple bond. What is the approximate bond angle of this carbon atom ?
I tried 180

I tried these answers but it's incorrect, i do not know what else to do, or i guess i really need help with angles, can anyone help me out? thank you so much!!!

A single atom does not have a bond angle, you need 3 to define it.

Does your program need units or similar?
