Question

1. Find the length of the missing side. Round your answer to the nearest

Answer 1

Answer:

x = 15

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

b and c are the other two sides

So we have

${x}^{2} = {12}^{2} + {9}^{2} \\ {x} = \sqrt{ {12}^{2} + {9}^{2} } \\ x = \sqrt{144 + 81} \\ x = \sqrt{225}$

We have the final answer as

x = 15

Hope this helps you
