What we teach in the UK to pre-university students is that tetrahedral bond angles decrease by about 2.5 degrees for every lone pair. Since in water (and OF2) there are two lone pairs on the O atom, I would expect the bond angle to be about 104.5 degrees.

OF2 is just like H2O except H replaced by F.
So, the bond angle is 109.5 degree.
I am sure it is not the actual angle. As a former professor, I am sure a teacher would not expect any student, even in college, don't mention HS, to come up with an exact value.
To response to those answers below. I agree in college students should know to subtract 2.5 degree for each lone pair. It depends on the audience. A 17 yr high school student may not have the experience yet.
