Answer:
3cm I think that's the answer
Step-by-step explanation:
45°, 45°, 90° triangle theorem states that:
Lengths of the sides opposite to the 45° angle are equal to one upon root two times of the length of hypotenuse.
Mathematically it can be expressed as:
![length \: of \: sides \: opposite \: to \: 45 \degree \: \\ angle \\ = \frac{1}{ \sqrt{2} } \times length \: of \: hypotenuse.](https://tex.z-dn.net/?f=length%20%5C%3A%20of%20%5C%3A%20sides%20%5C%3A%20opposite%20%5C%3A%20to%20%5C%3A%2045%20%5Cdegree%20%5C%3A%20%5C%5C%20%20angle%20%5C%5C%20%20%3D%20%20%5Cfrac%7B1%7D%7B%20%5Csqrt%7B2%7D%20%7D%20%20%5Ctimes%20length%20%5C%3A%20of%20%5C%3A%20hypotenuse.)
