Answer:

The correct answer option is a. m∠1 = 75 because corresponding angles of parallel lines are congruent.

Step-by-step explanation:

We are given a figure having lines that intersect each other, thus creating a number of angles.

We know that angles having the same relative position at each intersection  where a straight line crosses two parallel lines, then these angles are corresponding angles.

So here, m∠1 = 75 because corresponding angles of parallel lines are congruent.
