Nick has a square sheet of paper 15 centimeters on a side. He folds the paper along the diagonal and makes a 45degree - 45 degree - 90degree triangle. Find the length of the hypotenuse of this triangle

15√2

Step-by-step explanation:

They tell us the triangle was made from a 15cm sided square sheet. These sides will be our A and B in the pythagorean theorem:

C² = A² + B², C is the hypotenuse. Solving:

C² = 15cm² + 15cm² = √ (15cm) ² + (15cm) ²

C = 15√2
