Final answer:
Without a diagram or additional information, it's not possible to accurately determine which angles are congruent to an angle measuring 25 degrees when lines l and m are intersected by transversal t.
Step-by-step explanation:
The question asks us to determine which angles are congruent to an angle measuring 25 degrees when lines l and m are intersected by a transversal t. Without a specific diagram, we can apply general rules of geometry to infer possible congruent angles.
Assuming angle 25 is given and it's located at the intersection of lines l and m with transversal t, typical corresponding, alternate interior, or alternate exterior angle relationships could lead to congruent angles. But without the visual reference of the angles' positions or additional information, it is not possible to accurately determine which angles №1, №3, №5, №7 are congruent to an angle measuring 25 degrees.
In scenarios involving transversals and two intersecting lines, congruent angles are usually found opposite across the transversal (alternate exterior angles) or across the intersection point on different lines (alternate interior angles). Directly across the intersection on the same line would be corresponding angles.
