You can put this solution on YOUR website! Imagine that the sides are connected at one end and laying
right on top of eachother. Then imagine that one of the sides
is rotated a tiny fraction of a degree. The sides are now , , and plus a tiny length.
Arranged this way, the 3rd side can't be smaller than cm
---------------------------------------------------------------
Now leave the given sides connected at one end, but rotate them
so they are 180 degrees opposite eachother. They now add up to . Now rotate one of the sides a tiny fraction
of a degree. The sides are now {, , and minus a tiny length.
Arranged this way, the 3rd side can't be greater than cm
----------------------------------------------------------------
The 3rd side has to be in this range, 3 cm to 7 cm
