OpenStudy (heart_offire):

|dw:1481240435913:dw|

OpenStudy (mathsucks321):

I got 3

OpenStudy (heart_offire):

oh ok i was between 3 and 1

OpenStudy (mathsucks321):

Explain to me how you got 1

jhonyy9 (jhonyy9):

bc. angle A and angle B are congruent so equal from this result that these opposite sides are congruent too so this mean that you can writing 7x-6=5x yes ?

OpenStudy (mathsucks321):

5*1=5 7*1-6=1 They are not equal. ^.~

jhonyy9 (jhonyy9):

angle a and angle b has a measure of 54 degrees what mean that are equal angles yes ?

OpenStudy (heart_offire):

well i did it on a calculator and it came up 1.5something

OpenStudy (heart_offire):

@jhonyy9 yes the bas angles are equal

OpenStudy (heart_offire):

*base

jhonyy9 (jhonyy9):

7x-6=5x than we can writing this

jhonyy9 (jhonyy9):

from what you can easy calculi the value of x sure yes ?

jhonyy9 (jhonyy9):

so how many will be ?

OpenStudy (heart_offire):

no because i tried figuring the equation out but i couldnt so thats why i posted it here

jhonyy9 (jhonyy9):

7x-6 = 5x subtract from both sides 5x what will get ?

OpenStudy (heart_offire):

i get 7x-1=x

jhonyy9 (jhonyy9):

7x-5x-6 = 5x-5x do you can continue it please ?

OpenStudy (heart_offire):

i subtracted

jhonyy9 (jhonyy9):

please show your work step by step for i can check it how you get this result

OpenStudy (heart_offire):

7x-6=5x -5x -5x --------- 7x-1=x

jhonyy9 (jhonyy9):

no 7x-5x -6 = 5x-5x 2x -6 = 0 add to both sides 6 2x-6+6 = 0 +6 2x = 6 divide both sides by 2 x = 6/2 x = ?

OpenStudy (heart_offire):

x=3.......i subtracted from the wrong side lol sorry

jhonyy9 (jhonyy9):

yes x=3 this is the right answer sure hope you understand it now yes ?

OpenStudy (heart_offire):

yes thats the right answer, thanks

jhonyy9 (jhonyy9):

yw was my pleasure good luck bye bye
