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>
Answer:
15x + 2x can be written as 17x
Answer:
5.7 meters
Step-by-step explanation:
Image a rectangle being cut diagonally in half, that would lead to two triangles. We can use the pythagorean theorem to find the missing side.
7 is the hypotenuse and 4 is the side length
4^2+x^2=7^2
16+x^2=49
sqrx=sqr(49-16)
x=sqr33
x=5.74
Rounded to the nearest tenth is 5.7
Answer:
14

its an formula which comes in algebraic expression
The answer would be 8. hope this helps
