Answer 1

109° is the  answer.....hope it helps you

Answer 2

The angle which corresponds to the hybridization of sp^{2} is 120 degrees.

Answer: Option ii, 120 degrees

Explanation:

The hybridization of $sp^{2}$ has orbital of s donating 33 percent to the structure and 2 orbitals of p, donating rest of the percentage to the molecule. The shape of the molecule thus acquires a shape of trigonal planar where it is angled at 120 degree to each other. Hybridisation is the process of orbital mixing.
