Answer by addingup(3677)   (Show Source):
You can put this solution on YOUR website! the angle at the bottom of y is 90 degrees on either side of the line. Which means y is a perpendicular line. It seems to divides your christmas tree into two identical triangles, except that at the bottom you show a 4 9. If these are meant to show the length of the base, is the base 49 long? Or is one-half of the base 4 and the whole length 9?
To me it doesn't make sense because I would expect y to divide the christmas tree into two identical right triangles, so each half of the base would have the same length.
Also, to get the length of x, which is what you are asking, you need one more measurement. It can either be a side, for example the length of y, or either the angle at the top of line x, or at the bottom of line x.
