X has a value of 4.8
We can find this by saying that the ratio of side QR (5) to side MN (3) is the same as the ratio between side SR (8) and side ON (x)
This is because corresponding sides of similar shapes will have the same ratios
Our equation will look like:
5/3=8/x
5x=24 (using crossing multiplication)
X=4.8
