B 9 15 С A Find the length of AC. a 50.6 b 39.4 C 31.64 d 17.49

The answer would be -3.9> -4.5

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.
