Answer:

x = 5

Explanation:

You want the length of x in the figure showing similar triangles.

Proportion

The bottom edge of the triangle is 2/3 of the left edge.

The similar triangles have the same ratio of side lengths. That means x is 2/3 of (3+4.5):

(2/3)(7.5) = 5

The length x is 5 units.
