Two of the sides of a triangle are 18 and 25. The length of the third side is also a positive integer. How many different possible values are there for the third side length? (Assume that the triangle is non-degenerate.)

 

Please explain with your answer if you can, thank you!

Hint,

any side must be shorter than the sum of the other two sides.

(Otherwise the sides could not join up)

Draw it and see what I am saying.

 

Now you can work it out.
