in a triangle /the small side is x+6 one side at the bottom is 20/ another side divid by a line start from the angle cross from it and mark 1 part is x /another part is 8/what is valuae of x

Answer 1

Rather than the convoluted description above, indicate points and lengths.

For example, in triangle ABC, point D is on AB such that AD=3 and DB = 8.

That will make it much easier (and maybe possible at all) to figure out the question. From that point, getting the answer will be relatively easy.
