A right triangle has a hypotenuse of length 102–√

and an angle of 45 degrees, with a side opposite this angle with a length of 10. A second right triangle also has an angle of 45 degrees, with a side opposite this angle with a length of 14. Determine the length of the hypotenuse in the second triangle.

In a 45-45-90 right triangle, the relationship between the lengths of the sides is given by the ratios: both legs are equal, and the hypotenuse is \(\sqrt{2}\) times the length of each leg.

In the case of the second triangle, we know that the length of the leg (the side opposite the 45-degree angle) is 14.

To find the hypotenuse, we can apply the formula for a 45-45-90 triangle:

\[ \text{Hypotenuse} = \text{leg} \times \sqrt{2} \]

Substituting in the value of the leg:

\[ \text{Hypotenuse} = 14 \times \sqrt{2} = 14\sqrt{2} \]

Thus, the length of the hypotenuse in the second triangle is:

The hypotenuse of the second triangle has a length of \(14\sqrt{2}\).
