ABC is an isosceles triangle. If m(A) = 2b and m(B) = 3b - 10°, what's the value of m(C) and of b? (if you could answer the question in a deductive proof method, it'd be much appreciated, but it's not a must)

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
