Two parallel lines are cut by a transversal as shown below. Solve for B. Then explain your reasoning 56

56

What is the solution when solved for b, and why?

A

- 4 because attemate exterior angles are congruent. Therefore, 5 + 56 56

B

b = 70, because corresponding angles are congruent Therefore, D + 56 = 50.

000

с

0 = 56, because alternate interior angles are congruent Therefore 5 + 56 - 50

D

14, because vertical angles are congruent Therefore, 5 - 56 - 50
