In the drawing below, line n is a transversal that intersects two parallel lines. What is the measure of Angle 4?
40°
50°
130°
140°

Answer:
140°
Step-by-step explanation:
<3 = 40 because they are vertical angles
<3 +<4 = 180 because they are same side interior angles
40 + <4 = 180
Subtract 40 from each side
40-40 + <4 = 180-40
<4 = 140
