OpenStudy (anonymous):

where is figure..??

OpenStudy (anonymous):

what figure?

OpenStudy (anonymous):

:( there is no figure

OpenStudy (anonymous):

information about question is not sufficient to solve it..

OpenStudy (anonymous):

lol thanks

OpenStudy (anonymous):

is m<4 = m<8...??

hartnn (hartnn):

i suppose they are vertical angles like this |dw:1351175799591:dw| in that case they are equal, 3x=x+40 now solve this to get x

OpenStudy (anonymous):

If they are equal then answer will be 20...

OpenStudy (anonymous):

i got 4 llol

hartnn (hartnn):

3x=x+40 subtract x from both sides , what u get ?

OpenStudy (anonymous):

3x

OpenStudy (anonymous):

how are you soposed to subract x from both sides

OpenStudy (anonymous):

3x=x+40 subtract "x" on both sides.. 3x - x = x - x +40 2x = 40 divide both sides by 2.. you'll get the answer as I have written above..

hartnn (hartnn):

like this: 3x = x+40 3x - x = x-x +40 x(3-1) = 0+40 2x=40 got this ?

OpenStudy (anonymous):

ohhhhhhh so 3x-1x=40 he 2x=40 he 20

OpenStudy (anonymous):

equals

hartnn (hartnn):

yes, then x=20

OpenStudy (anonymous):
