Question

Find the value of x in the triangle shown below.
12

Answer 1

The answer is option C

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

c² = a² + b²

where

c is the hypotenuse

From the question x is the hypotenuse

So we have

`{x}^(2) = {5}^(2) + {12}^(2) \\ x = √(25 + 144) \\ x = √(169)`

We have the final answer as

x = 13
