Question 258829
Describe the possible lengths of the third side of the triangle given the lengths of the other two sides 4 inches, 7 inches

3 sides: x=4, y=7, z=?

|y-x| < z < x+y    (the || is absolute value)
okay since x and y are connected-->
if z=x+y the angle between x and y would be 180 and since there are 180 degrees in a triangle that could not be possible AND -->
if |y-x|=z then the angle between x and y would be 0 and that could not be a triangle either

3 < z < 11
