Transversal EF cuts parallel lines AB and CD as shown in the diagram, and m∠4 = 55.1°. What are m∠5 and m∠7?
Accepted Solution
A:
m < 5 = 55.1°
Due to the fact that <4 and <5 are vertical angles, their measurements are the same.
m < 7 = 124.9°
Due to the fact that <3 and <7 are corresponding angles, you can conclude that <4 and <7 are supplementary (their angles together have a sum of 180°) angles.
