Please use the ADD DETAILS feature to specify precisely where/how you need help. Right now it just looks as though you want/expect someone else to do the work for you. I trust it is not your intent to submit someone else’s work as your own.

1) I don’t remember the theorem but it has to do with parallel lines and a transversal.

2) exterior alternate angles are congruent

3) Since supplementary angles add to 180 degrees and angle 5 is congruent to angle 7, then angle 7 + angle 6 add to 180 degrees

4) need more info, is b cutting through c?

if so, then it needs to be stated that b is perpendicular to c, then you can say if b is perpendicular to c, then it is also perpendicular to d because c is parallel to d.
