The answer to the solution is X+3<19-x.
The answer is highlighted and I put the work for checking the answer at the bottom
60 divide dos by 15 is 4, so it takes 4 minutes for each person to empty it.

AB is the longest side, so ∠C is the largest angle.
use law of cosine: 16²=9²+12²-2*9*12cosC
216cosC=81+144-256=-31
cosC=-0.14352
C≈98
