[tex]x\text{ = }\sqrt[]{11}\text{ in}[/tex]
Here, we want to calculate the length of the missing side
From the given figure, we can see that the missing side faces the right angle
The side that faces the right angle is the longest side and it is called the hypotenuse
Mathematically, according to Pythagoras' ; the square of the hypotenuse equals the sum of the squares of the two other sides
We have this as;
[tex]\begin{gathered} x^2=2^2\text{ + (}\sqrt[]{7})^2 \\ x^2\text{ = 4 + 7} \\ x^2\text{ = 11} \\ x\text{ = }\sqrt[]{11\text{ }}\text{ in} \end{gathered}[/tex]
