In the figure, lines a, b, and c are parallel and m∠4=156° . drag and drop the correct angle measure for each angle.

Step-by-step explanation:

Part 1) If line a is parallel to line b

then

-----> by alternate exterior angles

so

we have

therefore

Part 2) we know that

-----> by supplementary angles

we have

substitute

Part 3) If line a is parallel to line b

then

-----> by alternate interior angles

so

we have

therefore

Part 4) If line b is parallel to line c

then

-----> by corresponding angles

so

we have

therefore
