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 square. the height - to - width ratio of each triangle is the square of the line.

Explanation:

Step1: Identify height and width for a triangle

For the first triangle, height is 4000 and width is 2. For the second, height is 10000 and width is 5.

Step2: Calculate height - to - width ratio

Using the first triangle: $\frac{4000}{2}=2000$. Using the second: $\frac{10000}{5}=2000$. So the ratio is 2000.

Answer:

2000
