Option D: 140° is the right answer
Step-by-step explanation:
In the given figure, a traversal is intersecting two parallel lines.
When two parallel lines are intersected by a traversal 8 angles are formed.
Corresponding angles:
Corresponding angles have same relative position when two parallel lines are intersected by a traversal So in the given figure the corresponding angles are:
m∠1 and m∠5
m∠2 and m∠6
When two parallel lines are intersected by a traversal, the corresponding angles are equal
So,
m∠1 = m∠5
m∠5 = 140°
Hence,
Option D: 140° is the right answer
