In triangle xyz, the length of side xy is 21 mm and the length of side yz is 31 mm. which of the following could
be the length of side xz?

There are two possible answer answer is this problem since no diagram is given

First if XZ is the longest side

XZ < Xy + YZ

XZ < 31 + 21

The possible length of XZ = 51 mm

If XZ is not the longest length

YZ < XZ + XY

31 < 21 + XZ

So the possible length of XZ = 11 mm

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right

no one knows lol
