I don't know how to do the last problem, sorry.

You are trying to find the angle at point F. Line AB and DF are parallel.

∠B is the same as∠C, so ∠C = 120°

A straight line is 180°. To find the other angle of the triangle, you do this:

120 + ? = 180

? = 60°

Now that you know 2 of the 3 angles, you can find angle F.

60 + 33 + ∠F = 180

∠F = 87°
