Answer 1

Answer:

The first one is in a straight line; The Second one is in a straight line; The Third one is not in a straight line

Step-by-step explanation:

1) The first one is in a straight line as whatever x maybe it will result in 180 as the answer.

2) The Second one is in a straight line as to when 97 is added with 83 it gives us 180 and 180degree forms a straight line (supplementary angle)

3) The Third one is not in a straight line as they add up to 200 which is more than 180.
