I'll draw it really quickly
I think it has something to do with interior angles but I get lost after that
so we know 2x+1=85
and 85+(3y+5)=180 since a+b=180
we know that 2x+1=85 because it is congruent to the one that says 85, right?
the angle that has measure 2x+1 and the angle that has measure 85 are called alternate interior angles
so the angle that has measure 2x+1 and the angle that has measure 85 are congruent therefore 2x+1=85
Ohhh okay, now I can get y, which would be 85+(3y+5)=180
But what about x?
what do you mean about x?
you have to both equations
2x+1=85 and 85+(3y+5)=180
Ohhh okay sorry I totally missed that. Thank you very much I understand it better now
http://www.mathwarehouse.com/geometry/angle/parallel-lines-cut-transversal.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
It 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
