Answer:

3

Explanation:

You want to know the value of the short side of the smaller of two similar triangles when the side ratio in the larger is 5 : 7.5, and the longer side in the smaller triangle is 4.5.

Proportional

Corresponding side lengths are proportional in these similar triangles:

x/4.5 = 5/7.5

x = 5(4.5/7.5) = 5(3/5)

x = 3

The length of x is 3.
