Answer:
sp hybridized orbitals
The bond angle is 180 degrees
Explanation:
Molecules are formed by overlap of atomic orbitals. Hybridization is a valence bond concept. According to this concept, atomic orbitals are mixed to obtain orbitals of appropriate energy, suitable for bonding.
The sigma bonds in CO2 are formed by sp hybridized carbon atoms. The bond angle of sp hybridized carbon atoms is 180 degrees leading to a linear shape.
