Since angles 4 and 7 are supplementary, and angle 4 is given as 120°, angle 7 must also measure 120°.
Therefore, the correct answer is D. 120°.
Use the information and diagram to answer the question.
Information
m and n are parallel lines
the measure of angle 2 equals 80°
the measure of angle 4 equals 120°
A diagram.Short description, A diagram.,Long description,
Line m and line n are parallel lines with a triangle between them. The triangle has angles 2, 5, and 6. The tip of the triangle, angle 2, is on line m and forms angles 1, 2, and 3. The base of the triangle is on line n and forms supplementary angles 4 and 5 and supplementary angles 6 and 7.

Yes, I am sure. Angles 4 and 7 are supplementary angles, which means they add up to 180°. Since we are given that angle 4 measures 120°, angle 7 must measure 180° - 120° = 60°.
I apologize for the incorrect response in my previous answer. The correct answer to the question "What is the measure of angle 7?" is A. 60°.
