To find the measure of angle 7 when angle 1 is 58°, we can use the property of alternate interior angles formed by a transversal cutting through parallel lines.
Since angle 1 and angle 7 are alternate interior angles, they are equal. Therefore, angle 7 also measures 58°.
The correct answer is:
1) 58°
