Answer:
We actually can't answer this because we need at least one angle in the triangle. However, the unknown length has a range. And the range is:
3<C<9. This is from the triangle inequality.
The solution would be to simply move the decimal point 2 places to the left to obtain your answer in standard form, in this case it would be 0.02345.
The greatest common factor is 38.
-6,-7, and -8, this is more of a guess and check question
