Answer:

x = 14

Step-by-step explanation:

Hi,

To begin, distribute the 2 to the x and -9.

So...

2 ( x - 9 ) = 10

2x - 18 = 10

2x = 28

x = 14

I hope this helps :)

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:-

$altitude^{2} + base^{2} = hypotenuse^{2}$

The base is 120cm and the hypotenuse is 122cm

Putting this in the equation, we get:-

$altitude^{2} + 120^{2} = 122^{2}$

$altitude^{2} = 122^{2}- 120^{2}$

$altitude^{2} = 14884 - 14400$

$altitude^{2}$ = 484

altitude = $\sqrt{484}$

<h3>altitude = 22cm</h3><h2><u>So, x = 22cm</u></h2>

Basile [38]

Answer:

x = 9

Step-by-step explanation:

The big triangle is similar to smaller one so we can use the side lengths' proportion to find x:

7/4 = (x-3)+8/8

7/4 = (x+5)/8 cross multiply expressions

56 = 4x + 20 subtract 20 from both sides

36 = 4x divide both sides by 4

9 = x
