Question

For the following right triangle, find the side length x.
X
9
12

Answer 1

it's the square root of 63 and I'd assume rounding to the tenth but I dont know how ur teacher does it.

Explanation:

find a calculator if u have one then solve for the square root of 63. this method is called the pythagorean theorem that i used

Answer 2

The calculated side length x in the right triangle is 15

How to determine the side length x in the right triangle

From the question, we have the following parameters that can be used in our computation:

The right triangle

Using the Pythagoras theorem, we have

x² = 9² + 12²

So, we have

x² = 225

Take the square root of both sides

x = 15

hence, the side length x in the right triangle is 15
