I do not understand your

m<C=2m<b,m<A=6m<B.

In our general usage of angles and sides, a capital letter usually stands for an angle, a small letter stands for the length of the opposite side to that angle,

there also seems to be a missing equal sign.

If you are saying

angle C = 2m

angle B = m

angle C = 6m

then we know ...

2m + m + 6m = 180

9m = 180

m = 20

so angle C = 2(20) = 40°
