X should equal 12.5
You have to split the isosceles acute triangle in the middle of the polygon down the middle, and find what the now right isosceles tringle is. Since we already know that there's a 50 degress and a 90 degress there all you have to do is add those two numbers together and subtract from 180. Thena after you've done that you just need to multiply 40 by 2 and bata bing, bata boom you have 80 degress as your top, you already have a 50 and the last one has to be 50. Divide 50 by 4 and you get 12.5
50+90=140
180-140=40
40 * 2 = 80
80 + 50 + x = 180
x= 50
4*x= 50
x=12.5
The diagram that shows all the lines of symmetry is diagram B.
<h3>
Which diagram shows all the lines of symmetry of the regular hexagon?</h3>
We define a line of symmetry as a line such that if we perform a reflection over that line, the <em>image coincides with the preimage </em>(so the reflection does not change the figure).
<em />
With that in mind, any line that cuts the hexagon in exactly two halves is a line of symmetry.
So the image that shows all the lines of symmetry of the regular is B, where it shows all the lines that cut the hexagon in two equal halves.
