So, 20.7 units below the water's surface
Sum of two sides always greater than the third side
If c is the smallest number, then
5 + c > 7
c > 2
If c is the largest number, then
5+7>c
12>c
Adding c>2 and 12>c, you get 12>c>2 for the answer
I belive its D dont take my word for it but i belive that is the answer
