angles Q.21 2E

How do you know that the angle is 107 specifically and not just less than 109.5?

We don't have to know the specific angle. Knowing that it's less than 109.5 is enough.

He mentioned this in lecture, but I believe we don't need to memorize the exact number, just that it's slightly less than 109.5.

Hi Monica! When I answered this, I just put slightly less than 109.5 as well. I remember both Lavelle and my TA mention that the specific angle was not required since it does differ between different atoms.
