Answer:
<h2>For the first triangle, <u>x equals 22cm.</u></h2>
Here's how:-
x is the altitude or height of the triangle. To find it, we can use the Pythagoras theorem:-
![altitude^{2} + base^{2} = hypotenuse^{2}](https://tex.z-dn.net/?f=altitude%5E%7B2%7D%20%2B%20base%5E%7B2%7D%20%3D%20hypotenuse%5E%7B2%7D)
The base is 120cm and the hypotenuse is 122cm
Putting this in the equation, we get:-
![altitude^{2} + 120^{2} = 122^{2}](https://tex.z-dn.net/?f=altitude%5E%7B2%7D%20%2B%20120%5E%7B2%7D%20%3D%20122%5E%7B2%7D)
![altitude^{2} = 122^{2}- 120^{2}](https://tex.z-dn.net/?f=altitude%5E%7B2%7D%20%3D%20%20122%5E%7B2%7D-%20%20120%5E%7B2%7D)
![altitude^{2} = 14884 - 14400](https://tex.z-dn.net/?f=altitude%5E%7B2%7D%20%3D%2014884%20-%2014400)
= 484
altitude = ![\sqrt{484}](https://tex.z-dn.net/?f=%5Csqrt%7B484%7D)
<h3>altitude = 22cm</h3><h2><u>So, x = 22cm</u></h2>
