@ParthKohli does that mean my other answers are right?

number 1 is wrong.. <1 and <2 are supplementary...but they're not congruent

remember the transversal law.. dw:1349494407179:dw the angles with one line are congruent to the angles with one line...angles with two lines are congruent to angles with two lines

Yeah, I guess. I thought that question 1 was <7

look closely at my drawing... these are the angles that are congruent dw:1349494548934:dw
 one year ago

lgbasalloteBest ResponseYou've already chosen the best response.5
now.. angle 1 is heredw:1349494584613:dw
 one year ago

lgbasalloteBest ResponseYou've already chosen the best response.5
so what angle do you think is congruent to it?

lgbasalloteBest ResponseYou've already chosen the best response.5
that drawing is also applicable to your question 3

KatherinePierce1864Best ResponseYou've already chosen the best response.2
so 3 isnt 42?

lgbasalloteBest ResponseYou've already chosen the best response.5
as for number 2..you can figure it out by looking at <1 and <8...if you notice, they are both OUTSIDE and on DIFFERENT SIDES do those capitalized words give you any hint?
 one year ago

KatherinePierce1864Best ResponseYou've already chosen the best response.2
does that mean there exterior?

@lgbasallote I have another problem, like the one above, do you think you can help me with that one as well??

4. What is the value of x? (1 point) 10o 25o 30o 120o 5. What is the measure of 1? (1 point) 45o 60o 120o 125o

here's a hint 4x and x+ 30 are supplementary angles
 one year ago

lgbasalloteBest ResponseYou've already chosen the best response.5
do you know what that means?
 one year ago

KatherinePierce1864Best ResponseYou've already chosen the best response.2
no, sry. do you mind explaining a bit more?
 one year ago

lgbasalloteBest ResponseYou've already chosen the best response.5
supplementary angles means that if you add 4x and x + 30 you get 180
 one year ago

lgbasalloteBest ResponseYou've already chosen the best response.5
so add 4x and x + 30 and set it equal to 180 then solve for x
 one year ago

KatherinePierce1864Best ResponseYou've already chosen the best response.2
i think so
 one year ago

KatherinePierce1864Best ResponseYou've already chosen the best response.2
doesn't it come to 5x+30, or am I way off?
 one year ago

lgbasalloteBest ResponseYou've already chosen the best response.5
now make it equal to 180 then solve for x
 one year ago

KatherinePierce1864Best ResponseYou've already chosen the best response.2
okay so wouldn't add 5 to 30 or times 30 by 5? hope that makes sense.
 one year ago

lgbasalloteBest ResponseYou've already chosen the best response.5
5x + 30 = 180 solve for x
 one year ago

KatherinePierce1864Best ResponseYou've already chosen the best response.2
would a way to solve the problem be by taking 30 away frm 180 then dividing by that number by 5?
 one year ago

KatherinePierce1864Best ResponseYou've already chosen the best response.2
okay, what about the next question?
 one year ago

lgbasalloteBest ResponseYou've already chosen the best response.5
you already have the value of x..so just substitute that to x + 30
 one year ago

KatherinePierce1864Best ResponseYou've already chosen the best response.2
Oh right, so 60 then.
 one year ago

KatherinePierce1864Best ResponseYou've already chosen the best response.2
okay, thank you so much!
 one year ago

KatherinePierce1864Best ResponseYou've already chosen the best response.2
actually the answer was 120 for the last question. :p does that make sense to you?
 one year ago

lgbasalloteBest ResponseYou've already chosen the best response.5
....sorry i thought 1 was at x + 30
 one year ago

lgbasalloteBest ResponseYou've already chosen the best response.5
it seems 1 is the supplement of x + 30 so you have to subtract 60 from 180
 one year ago

KatherinePierce1864Best ResponseYou've already chosen the best response.2
oh okay. Now I know and its okay. I still got a 80% on the test so its cool.
