In the diagram below, BD is parallel to XY. What is the value of x?
Note: BD and XY have the little line over them but I have no idea how to put it.

I'd say 55. Am I right? Or it's 125?

HINT: x and 125 are supplementary...

How do I know if they're supplementary?

because it's a straight line

they're a linear pair

It would add up to equal 180

How do I know if I should put 55 or 125 because last time I did a problem like that and the answer was the same as 125.

Does it have to do with the lines? For example this question:

Its the lower angle (It looks smaller so it has to be 55)

^ The answer for that one was 67.

right, because those angles were alternate exterior angles

marcoduuuh Group TitleBest ResponseYou've already chosen the best response.0
Supplementary lines: subtract from 180. Alternate exterior angles: the same as the other line. Am I right? If yes, how do I know the difference from both of the different lines?

AriPotta Group TitleBest ResponseYou've already chosen the best response.2
that shows congruency
 2 years ago

AriPotta Group TitleBest ResponseYou've already chosen the best response.2
and any angles who are on a straight line add up to 180
 2 years ago

AriPotta Group TitleBest ResponseYou've already chosen the best response.2
because, it's a straight line and straight lines are 180 degrees
 2 years ago

AriPotta Group TitleBest ResponseYou've already chosen the best response.2
does that make sense?
 2 years ago

marcoduuuh Group TitleBest ResponseYou've already chosen the best response.0
I think so... Okay, let me see if I've got it. Okay, so for that one... That's a Alternate exterior angle?
 2 years ago

AriPotta Group TitleBest ResponseYou've already chosen the best response.2
those are corresponding angles
 2 years ago

Geometry_Hater Group TitleBest ResponseYou've already chosen the best response.2
X is corresponding
 2 years ago

AriPotta Group TitleBest ResponseYou've already chosen the best response.2
they are congruent too though
 2 years ago

marcoduuuh Group TitleBest ResponseYou've already chosen the best response.0
See... That's what I don't understand. How do you guys know they are congruent. Sorry. i'm stupid. :/

look at the pic i posted
 2 years ago

AriPotta Group TitleBest ResponseYou've already chosen the best response.2
it shows all angles that are congruent
 2 years ago

Geometry_Hater Group TitleBest ResponseYou've already chosen the best response.2
All lines are 180. So whenever we have an angles like that they will always equal 180 degrees together

marcoduuuh Group TitleBest ResponseYou've already chosen the best response.0
Wait... I'm thinking haha.

marcoduuuh Group TitleBest ResponseYou've already chosen the best response.0
Okay, so if they're congruent that means they have the same number right? 110 would be the answer for that one?
 2 years ago

Geometry_Hater Group TitleBest ResponseYou've already chosen the best response.2
Thats right
 2 years ago

marcoduuuh Group TitleBest ResponseYou've already chosen the best response.0
Okay so for this one it isn't congruent am i right? so the answer would be 75?
 2 years ago

AriPotta Group TitleBest ResponseYou've already chosen the best response.2
those are congruent
 2 years ago

AriPotta Group TitleBest ResponseYou've already chosen the best response.2
they are also corresponding angles
 2 years ago

Geometry_Hater Group TitleBest ResponseYou've already chosen the best response.2
They are corresponding because they are in similar places

AHHHHHHHHHHHHHHHHHHH. I DON'T GET THIS.

Hmm hold on

dw:1349397323829:dw 1 and 5 would be corresponding angles because they are in the same places

AriPotta Group TitleBest ResponseYou've already chosen the best response.2
if you can read what i wrote lol.
 2 years ago

marcoduuuh Group TitleBest ResponseYou've already chosen the best response.0
I can! Wait... So that would mean every line is corresponding? Why do I sometimes have to put the same number that's on top and then other times i have to subtract from 180..
 2 years ago

Geometry_Hater Group TitleBest ResponseYou've already chosen the best response.2
Every line isnt corresponding......... For instance in my drawing 1 and 5 are corresponding but not 1 & 6
 2 years ago

AriPotta Group TitleBest ResponseYou've already chosen the best response.2
no, no. i mean those ANGLES are corresponding
 2 years ago

AriPotta Group TitleBest ResponseYou've already chosen the best response.2
the lines are parallel and cut by a tranversal which makes the angles i listed corresponding and congruent
