Give the approximate values for the indicated bond angles.
a. O-S-O in So2
b. F-B-F angle in BF3
c. Cl-C-Cl angle in CL2CO
answers in the back of the book
--------------------------------------…
a. slightly less than 120 degrees;The lone pair of S should reduce the predicted 120 degrees angle slightly. 120 degrees
b. 120 degrees
c. Slightly less than 120 degrees; The two lone pairs of electrons on O will reduce the predicted 120 degree angle slightly.

Seems you have approximate bond angles, are you after better explanations of justifications?

What do you know about VSEPR, or similar?
