Question

I need help to find x. Please help

Answer 1

x = 6

Explanation:

These triangles are similar shapes. They have the same shape but different sizes. This means there exists a scale factor between side lengths of the two triangles. They are related. You can find a missing side length by writing a proportion between the sides of each triangle.

`(x)/(x+2)=(9)/(12)\\ 12(x) = 9(x+2)\\12x = 9x + 18\\3x = 18\\x = 6`
