`\boxed{\boxed{\sf{ x=3 }}}`
`\sf{ }`

Answer 2

x is 3

Explanation:

You use proportions to figure out x, what you first do is set up the proportion of the big triangle, then the small triangle.

`((9+3))/(3)`=
`(12)/(x)`

By setting up this proportion, you would then cross multiply, and get 12x = 36. This is when you divide by 12 on both sides and get x=3
