Answer: 16.

Step-by-step explanation:

All angles in any pentagon add up to 540 degrees.

As such, you can represent each angle in an equation in which the sum of all the angles is 540, as follows:

$(12z-42)+(7z+24)+(z+38)+(6x+49)+(z+39)=540\\\\27z + 108 = 540\\27z = 432\\\\z=16$

19 wouldn’t be reasonable, but it’s a trick question, because it really depends on the weight of the items, but if we don’t know what items they are, then we have to predict that the biggest number would be to much, so I think it’s B, or 19.
Hope this helps.
