Answer 1

Это просто, 9/1,8 =11/х .Х= 2,2 метра.

Answer 2

Calculation of the Height of the Lantern

To calculate the height of the lantern, we can use the concept of similar triangles. Let's break down the given information:

- The person's height is 1.8 meters. - The person is standing 11 steps away from the pole. - The length of the person's shadow is 9 steps.

We can set up a proportion to find the height of the lantern:

Person's height / Person's shadow = Distance to the lantern / Height of the lantern

Let's substitute the given values into the proportion:

1.8 meters / 9 steps = 11 steps / Height of the lantern

To find the height of the lantern, we can cross-multiply and solve for it:

Height of the lantern = (1.8 meters * 11 steps) / 9 steps

Calculating this, we get:

Height of the lantern ≈ 2.2 meters

Therefore, the lantern is approximately located at a height of 2.2 meters.

Please note that the above calculation assumes that the person's height and the length of their shadow are proportional to the distance to the lantern and the height of the lantern.
