I don't think that anyone will be able to help you without the diagram, but this problem sounds like it could be a common type where there are two parallel lines cut by a transversal. (The diagrams look kind of like a road with two intersections.)
If this is the case, all of the eight angles in both intersections end up having one of two measurements. Four of the angles would be 125°, and the other four angles would all the be supplement, so 180 - 125 = 55°. You should be able to tell which are which by looking for the big angles and small angles.
If you want to reason through the problem, you can look for pairs of vertical angles, alternate interior angles, and corresponding angles (which are all congruent) and pairs of same-side interior angles (which are supplementary.)
If the problem you are referencing does not fit my description, please try to post a picture of the diagram if you can. Hope this help!
