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°
