Answer:
B
Step-by-step explanation:
Corresponding angles form a sideways U when you connect the angles.
b is the only one that does that.
1 and 4 are consecutive angles.
1 and 3 are vertical angles
4 and 3 are linear pair angles.
Cos^2 + cos^2 tan^2 (break the brackets)
Cos^2+ cos^2 • sin^2/cos^2 (divide out the cos^2)
Cos^2+ sin^2 (Cos2+ sin^2= 1)
= 1
