Is to long to explain so I'm doing quite
find the triangle side so 2.1 square minus 1.4 square it is equal to 2.45
now you just multiple 2.45 by 2 because if you notice 2.45 is the triangle side that is missing and this is only the half so multiple by 2 for get the X value, I hope this helps you.

Step-by-step explanation:
The rule for the reflection
rx-axis (x, y) → (x, –y)
ry-axis (x, y) → (–x, y)
<h3>Further explanation</h3>
A reflection is an example of a transformation
Reflection is the process of mirroring each point on the geometry of a certain line.
The original figure is called the pre-image and the final figure is called the image
The image will be congruent with the pre image and the distance of the image to the mirror axis is the same as the distance of the pre image to the mirror axis
There are several reflection equations:
- The equation of reflection across the<em><u> x-axis
</u></em>
x '= x
y '= - y
can be written
- The equation of reflection across the <u><em>y-axis
</em></u>
x '= x
y '= -y
can be written
- The reflection equation across the line <u><em>y = -x
</em></u>
x '= - y
y '= - x
can be written
- The reflection equation across the line x = h
x '= 2h-x
y '= y
can be written
- The reflection equation across the line y = k
x '= x
y '= 2k-y
can be written
So the correct rule for reflection is:
rx-axis (x, y) → (x, –y)
ry-axis (x, y) → (–x, y)
