Greater than zero and less than eleven.

The third side of a triangle must be greater than the absolute difference of the two given sides and less than the sum of the two given sides. In this case, the third side must be greater than |7-9| = 2 and less than 7+9 = 16. Therefore, the possible lengths for the third side of the triangle could be any value greater than 2 and less than 16.
It could be 12 because the sum of the 2 smaller sides of a triangle must be bigger than its largest side.

The third side can have any value in the range (2 cm, 16 cm).

The third side must be longer than 11 and shorter than 19.

For a triangle to exist, the sum of the two shorter sides must be longer than the longest side. If 15 is the longest side, then the other, missing, shorter side must be greater than 15 - 4 = 11. If the third, missing, side is the longest side, then it must be less than 15 + 4 = 19 So the third side is any length greater than 11 and less than 19. Examples include 12, 13, 15, 11.5, 18.5.
The third side can have any value in the range (2 cm, 16 cm).
It is a tangent.
Any value between 7 and 17------------------------------------To create a triangle, the sum of the two shorter sides must be greater than the third side.If the side of length 12 is the longer side then the missing side must be greater than 12 - 5 = 7If the missing side is the longer side then the missing side must be less than 5 + 12 = 17Thus any length that is greater than 7 and less than 17.-----------------------------------------------------------------------A Pythagorean triangle would have a hypotenuse of 13
Assuming that 15 and 12.5 units are measures of the lengths of two sides of the triangle, the third is any value in (2.5, 27.5) units
To find the length of PR, you can use the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. In this case, PR must be less than the sum of PQ and QR, so PR < 20 + 22 = 42. Therefore, PR could be any value less than 42.
It depends on what value you require: th length of a side, a measure of an angle, the area. And it also depends on what information you do have.
