Question

Find the exact length of the third side,

Answer 1

Answer:

The answer is

$\sqrt{41}$

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

${x}^{2} = {5}^{2} + {4}^{2} \\ x = \sqrt{25 + 16} \\ x = \sqrt{41}$

We have the final answer as

$\sqrt{41}$
