@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

got it?

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

lgbasallote Group TitleBest ResponseYou've already chosen the best response.7
now.. angle 1 is heredw:1349494584613:dw

lgbasallote Group TitleBest ResponseYou've already chosen the best response.7
so what angle do you think is congruent to it?
 2 years ago

KatherinePierce1864 Group TitleBest ResponseYou've already chosen the best response.2
5?

Oh okay

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?

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
 2 years ago

lgbasallote Group TitleBest ResponseYou've already chosen the best response.7
do you know what that means?
 2 years ago

KatherinePierce1864 Group TitleBest ResponseYou've already chosen the best response.2
no, sry. do you mind explaining a bit more?
 2 years ago

lgbasallote Group TitleBest ResponseYou've already chosen the best response.7
supplementary angles means that if you add 4x and x + 30 you get 180
 2 years ago

lgbasallote Group TitleBest ResponseYou've already chosen the best response.7
so add 4x and x + 30 and set it equal to 180 then solve for x
 2 years ago

lgbasallote Group TitleBest ResponseYou've already chosen the best response.7
get the idea?
 2 years ago

KatherinePierce1864 Group TitleBest ResponseYou've already chosen the best response.2
i think so

wonderful

doesn't it come to 5x+30, or am I way off?
 2 years ago

lgbasallote Group TitleBest ResponseYou've already chosen the best response.7
yes it does
 2 years ago

lgbasallote Group TitleBest ResponseYou've already chosen the best response.7
now make it equal to 180 then solve for x
 2 years ago

KatherinePierce1864 Group TitleBest 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.

5x + 30 = 180 solve for x
 2 years ago

KatherinePierce1864 Group TitleBest 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?
 2 years ago

KatherinePierce1864 Group TitleBest ResponseYou've already chosen the best response.2
x=30
 2 years ago

KatherinePierce1864 Group TitleBest ResponseYou've already chosen the best response.2
okay, what about the next question?
 2 years ago

lgbasallote Group TitleBest ResponseYou've already chosen the best response.7
you already have the value of x..so just substitute that to x + 30
 2 years ago

KatherinePierce1864 Group TitleBest ResponseYou've already chosen the best response.2
Oh right, so 60 then.
 2 years ago

KatherinePierce1864 Group TitleBest ResponseYou've already chosen the best response.2
okay, thank you so much!

welcome

KatherinePierce1864 Group TitleBest ResponseYou've already chosen the best response.2
actually the answer was 120 for the last question. :p does that make sense to you?

lgbasallote Group TitleBest ResponseYou've already chosen the best response.7
....sorry i thought 1 was at x + 30
 2 years ago

lgbasallote Group TitleBest ResponseYou've already chosen the best response.7
it seems 1 is the supplement of x + 30 so you have to subtract 60 from 180
 2 years ago

KatherinePierce1864 Group TitleBest 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.
