Can you please answer this ASAP)

Answer the question 1st:

1-corresponding angles=180

then,90+90=180

2-not parallel

3-not parallel

4-corresponding angles=180

          x+x=180

          2x=180

          x=180/2

          x=90degree

5-suppose x for two angles

then, same as 4 no. x + x=180

6= alternate angles are always equal.

what is the original number? you forgot to add it.
