XY = 14 mm , YZ = 15 mm , XZ = 30 mm

Question

solve Which of the following combinations of side lengths will form a triangle? XY = 14 mm , YZ = 16 mm , XZ = 29 mm
XY = 15 mm , YZ = 16 mm , XZ = 32 mm
XY = 13 mm , YZ = 16 mm , XZ = 30 mm
XY = 14 mm , YZ = 15 mm , XZ = 30 mm

anonymous · Answer

the first one : XY = 14 mm , YZ = 16 mm , XZ = 29 mm

14+16=30
Just in case so it's better if the summ of the two shorter sides is greater then the longer side.
