Help please i dont get it

x = 3

Step-by-step explanation:

1. Because the two triangles are similar, it means that the only difference between them is their side lengths.

2. To find x in similar triangles, you first have to find how many times larger one side length in a triangle is than the other. To do this, you have to divide one of the larger triangle's sides with the corresponding side of the smaller triangle.

3. 8 and 6 are corresponding, and so are 6 and 4.5. 8/6 is equal to 1 1/3, and 6/4.5 is also equal to 1 1/3.

4. Since the side lengths of the larger triangle is 1 1/3 greater than the other, (4/3)x = 4.

5. Now, let's solve the equation (4/3)x = 4

6. Therefore, x is equal to 3.
