The image shows a triangle formed by a plane's altitude, the horizontal distance to a point on the ground, and the slant distance (hypotenuse).

In the diagram:

• The horizontal distance is 770 meters.
• The slant (diagonal) distance is 850 meters.
• The altitude is unknown, and we are asked to solve for it.

This is a right-angled triangle, and we can use the Pythagorean theorem to solve for the altitude $h$, where:

$h^2 + 770^2 = 850^2$

Let's solve this equation to find the altitude.The altitude of the plane is 360 meters.

Would you like further details or have any questions about the calculation?

Here are five related questions to expand on this topic:

1. How would the altitude change if the horizontal distance were different?
2. Can you solve for the angle of ascent given the same distances?
3. How can we apply the Pythagorean theorem to other real-world scenarios?
4. How does this problem change if the triangle were not a right triangle?
5. What other trigonometric methods can be used to find the altitude?

Tip: When solving problems involving triangles, identifying whether it's a right triangle allows you to easily apply the Pythagorean theorem.
