    srry angle ABC+ 5x+(3x+16) =180

    ABC+8x+16=180 ABC+8x=164 ABC+x=

    well they are asking for equation \[ABC= -x+20.5\]

    because \[\frac{ 164 }{ 8 } =20.5\]

    I need to get the angle, not just the equation

    m<ABC=-x+20.5

    Yea, but how do I find the angle now

    you cant get the angle because we dont know the x variable

    or we can use substitution

    Then I guess that is the answer, thank you very much. Math can be a pain sometimes.

    yea it can but i dont think u would require substitution in this question
