Question

the two triangles have at least two pairs of congruent corresponding angles, so the two triangles are similar by the angle - angle theorem. thus, the two triangles have the same ratio of height to width. the height - to - width ratio of each triangle is equal to dropdown box. the height - to - width ratio of each triangle is the dropdown box of the line.

Explanation:

Step1: Calculate ratio for first triangle

For the first triangle, height is 4000 and width is 2. The ratio of height to width is $\frac{4000}{2}=2000$.

Step2: Verify with second triangle

For the second triangle, height is 6000 and width is 3. The ratio is $\frac{6000}{3}=2000$. So the height - to - width ratio is 2000.

Answer:

2000
