Answer:
3
Step-by-step explanation:
Triangles with the same shape but different size are proportional. Proportional means that their side lengths form equal ratios. To solve for x, set up a proportion.
The ratios we will create will be
where each long and short are corresponding sides from each triangle.
So write:

To solve, cross multiply numerator with denominator.
4(2.25) = 3(x)
9 = 3x
3 =x
