Question 368320
How do you find the range for the measure of the thrid side of a triangle givn the measure of two sides which are 7 and 9?

Let x = the range for the measure of the 3rd side of triangle

   (9-7) < x < (7+9)
  
       2 < x < 16

The range for the measure of the thrid side of a triangle is any number greater than 2 but less than 16.
