please help me!!!!!!!!!!!!!!!!!!!!

OpenStudy (lgbasallote):

use ratio and proportion \[\frac{6}{30} = \frac{11}{x}\] does that help?

OpenStudy (anonymous):

its 55 as ab/de=6/30=1/5 then df/ac=1/5 so 11/x=1/5 cross multiplying x=55

OpenStudy (raden):

m(C) = m(F), ?

OpenStudy (anonymous):

could the answer could also be 16.36

OpenStudy (lgbasallote):
