I have another question (then another one) but I am really just trying to understand this. So there are two horizontal pararell lines intersected by a transversal.

Best ResponseYou've already chosen the best response.0I think it has something to do with interior angles but I get lost after that

Best ResponseYou've already chosen the best response.1and 85+(3y+5)=180 since a+b=180

Best ResponseYou've already chosen the best response.0we know that 2x+1=85 because it is congruent to the one that says 85, right?

Best ResponseYou've already chosen the best response.1the angle that has measure 2x+1 and the angle that has measure 85 are called alternate interior angles

Best ResponseYou've already chosen the best response.1so the angle that has measure 2x+1 and the angle that has measure 85 are congruent therefore 2x+1=85

Best ResponseYou've already chosen the best response.0Ohhh okay, now I can get y, which would be 85+(3y+5)=180

Best ResponseYou've already chosen the best response.1http://www.mathwarehouse.com/geometry/angle/parallellinescuttransversal.php here is site that you might like though in that first example where they talk about can you identify each type of congurent angle... I think the third column should read corresponding angles

Best ResponseYou've already chosen the best response.1It also mentioned something about a Z test never heard of that before now but you may find that test helpful it is for testing what angles are congruent
