Answer:

The answer is option C

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

We have

[tex] {13}^{2} = {5}^{2} + {x}^{2} \\ {x}^{2} = {13}^{2} - {5}^{2} \\ {x}^{2} = 169 - 25 \\ {x}^{2} = 144[/tex]

Find the square root of both sides

That's

[tex] \sqrt{ {x}^{2} } = \sqrt{144} [/tex]

We have the final answer as

x = 12

Hope this helps you
