Here, we want to calculate the measure of the two sides
As we can see, what we have is the measure of the hypotenuse
It is the side that faces the right-angle and also it is the longest side
The triangle is a 45-90-45 triangle
The measure of the opposite and the adjacent are the same
The ratio of the sides are;
![1\colon1\colon\sqrt[]{2}](https://img.qammunity.org/2023/formulas/mathematics/college/41tpjsiy7t1v94h6ct8dqgh148zi7wqje2.png)
We already have the root 2 part
So to get the value of the 1 ratio, we need to divide the hypotenuse by root 2
Mathematically, we have this as;
![\frac{3\sqrt[]{2}}{\sqrt[]{2}\text{ }}\text{ = 3}](https://img.qammunity.org/2023/formulas/mathematics/college/ugluskfqu6juili3asfs0bnv8wr1oqv3oy.png)
