It depends on the font. Let's assume the simplest form of the letter X, which is just the diagonals of a perfect square.
In that case there are four: one vertical, one horizontal, and one along each of the diagonals.
There's also technically a fourfold axis of rotational symmetry perpendicular to the page.
The letter X has two lines of symmetry. A line of symmetry is a line that divides an object into two equal halves that are mirror images of each other. In the case of the letter X, it can be divided vertically and horizontally into two equal halves, resulting in two lines of symmetry.

x= 5y+10 * * * * * That looks like a mistaken merge! A regular polygon with n sides has n lines of symmetry.
Of the capital letters M, O, E, and X, -- M and E each have one line of symmetry, -- X has two lines of symmetry, or four if the cross lines were printed perpendicular, as they are in some fonts, -- O has an infinite number of lines of symmetry. My answer is justified by my firm conviction that it's correct.
A dodecahedron has 30 lines of symmetry. This is because each face of a dodecahedron is a regular pentagon, which has 5 lines of symmetry. Therefore, each face contributes 5 lines of symmetry, and since a dodecahedron has 12 faces, the total number of lines of symmetry is 5 x 12 = 30.
the letter X has two lines of symmetry
If you mean the letter x, it has four lines of symmetry.
It has 2
2 lines of symetry

How about: X
Lower case "o" and "x" both have two lines of symmetry. Upper case letters with two lines of symmetry are: "O," "X," "H" and "I."
