bond angle of a compound can be found by gathering the information about its hybridisation?

for example: for NH3, its hybridisation is sp3,so bond angle is 104.50.

Dear Vaishal,

 One can never get correct bond angle by any formula always, bcoz of lone pair repulsions or due to lack of electrons, but here is a hyb. table, which would help you.

VSEPR table

The bond angles in the table below are ideal angles from the simple VSEPR theory, followed by the actual angle for the example given in the following column where this differs. For many cases, such as trigonal pyramidal and bent, the actual angle for the example differs from the ideal angle, but all examples differ by different amounts. For example, the angle in H2S (92°) differs from the tetrahedral angle by much more than the angle for H2O (104.5°) does.
