Best ResponseYou've already chosen the best response.0so you got this right? m<A=m<B right? so from here you can solve it :) it just gonna give you super ugly number though :)

Best ResponseYou've already chosen the best response.0if there were your answers then you should do this: m<A + m<B = 180 ( we don't need C since B = C) 40 + 3x +1 =180 41 +3x =180 3x= 139 x =46.3 :)

Best ResponseYou've already chosen the best response.0cuz if you use m<A = m<B is gonna give you 13. something ( very ugly)

Best ResponseYou've already chosen the best response.0Then to find \(x\), we know that a triangle has 180 degrees. So, \(<A+<B+ <C= 180\)

Best ResponseYou've already chosen the best response.0WRONG ANSWER~~~ you still need C since you gonna = 180 cuz it 3 angles is sum of a triangle

Best ResponseYou've already chosen the best response.0so like you just : m<A + m<B + m<C =180 you got the second line so I skip~~ 6x +42 =180 6x = 138 x = 23 lol~~~
