Please Help me!

1. In the diagram below , lines a and b are parallel and cut by traversal, t of angle 3 is 120 degrees, find the measure of angle 7.

∡3=∡7------------- >  corresponding angles
the answer is ∡7=120 degrees

2. in the diagram below , lines a and b are parallel and cut by traversal, t of angle 2 is 50 degrees, find the measure of angle 8.

∡2=∡8------------- >  alternate exterior angles

the answer is ∡8=50 degrees

3. In the diagram below , lines a and b are parallel and cut by traversal, t of angle 6 is 50 degrees, find the measure of angle 4.

∡6=∡4------------- >  alternate interior angles

the answer is ∡4=50 degrees
