Find the exact length of the third side,

Answer:
The answer is
Step-by-step explanation:
Since the triangle is a right angled triangle we can use Pythagoras theorem to find the missing side x
Using Pythagoras theorem we have
a² = b² + c²
where
a is the hypotenuse
So we have
[tex] {x}^{2} = {5}^{2} + {4}^{2} \\ x = \sqrt{25 + 16} \\ x = \sqrt{41} [/tex]
We have the final answer as
[tex] \sqrt{41} \\ [/tex]
