<h2>
The Pythagorean Theorem</h2>
The Pythagorean Theorem: 
- <em>a</em> and <em>b</em> are the two legs in a right triangle
- <em>c</em> is the hypotenuse (the longest side of a right triangle; opposite the 90° angle
- <em>*keep in mind that this theorem applies only to right triangles</em>
<h2>Solving the Question</h2>
We're given:
- Legs = 9 units and 12 units
- Hypotenuse = <em>c</em>
<em />
Plug these measurements into the Pythagorean theorem:

⇒ Combine like terms:

<h2>Answer</h2>

6/10, 9/15,12/20, 15/25,...30/50, 33/55...300/500...
4x - 5(x - 2) = 12x + 4 - x
4x - 5(x) - 5(-2) = 12 - x + 4
4x - 5x + 10 = 11x + 4
-x + 10 = 11x + 4
<u>+ x + x </u>
10 = 12x + 4
<u>- 4 - 4</u>
<u>6</u> = <u>12x</u>
12 12
0.5 = x
The lines of symmetry in this particular picture are the horizontal and vertical lines.
If you were to look at the first quarter, and the vertical line reflects the curves to the second quarter.
Then, if you were to look at the horizontal line, you would see that the line reflects the entire top half to the bottom.
Hope this helps and please consider marking branliest.
