I got 135 because 45+135=180... is that correct?

In that trapezoid ∠F is opposite ∠H. No, opposite angles of a trapezoid are not generally supplementary. There is no relation that applies to opposite angles of all trapezoids. The correct answer could be any value greater than 0° and less than 180°.

Yes, angle H is the supplement of angle F.

You missed the word after "is a". But yes if it's a cyclic (inscribed) quadrilateral it's 135°.
