Answer :
No, we do not agree with Ted when he says that the possibility for the unknown side length is 40 as it would be: 15 + 27 = 42.
According to the law of the sides of a triangle, the lengths of any two of the triangle's sides added together are always more than the length of the third side. The triangle inequality theorem is another name for this condition. This indicates that a triangle with two sides equal to 15 and 27 would be having a third side more than 42 units.
The three vertices of a triangle connect the straight lines that make up its sides. In other words, we can say that the sides of a triangle are line segments that converge at the vertices of the triangle. A right-angled triangle's sides can be found using a variety of methods, including the Pythagoras theorem and the triangle's perimeter.

Complete question is:
A triangle has sides of 15 and 27. The measurement of the longest side is missing.
Ted says that one possibility for the unknown side length is 40. Do you agree with Ted? Why or why not?
