Mathematics
1 answer:
KATRIN_1 [288]3 years ago
3 0

Answer:

x = 6

Step-by-step 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.

\frac{x}{x+2}=\frac{9}{12}\\ 12(x) = 9(x+2)\\12x = 9x + 18\\3x = 18\\x = 6
