The 3rd side of a triangle with a side of 12 and one of 3 would have to be >12-3 and <12+3. Do you see why that is true?
OpenStudy (anonymous):
Answers A, B, and D don't make a triangle. One of the specifications for a triangle is that the sum of the other two sides must exceed the longest side. None of these combinations work. Since 10+3>12, answer C will work.
