For a right triangle with an angle of 45 degrees, we can use the properties of 45-45-90 triangles. In such a triangle, the lengths of the legs are equal, and the hypotenuse can be calculated using the formula:
\[ \text{hypotenuse} = \text{leg} \times \sqrt{2} \]
Given that the second triangle has a leg (the side opposite the 45-degree angle) of length 14, we can find the length of the hypotenuse as follows:
\[ \text{hypotenuse} = 14 \times \sqrt{2} \]
Thus, we can conclude that the hypotenuse of the second triangle has a length of \( 14\sqrt{2} \).
The correct response is: The hypotenuse of the second triangle has length \( 14\sqrt{2} \).
