Question

Человек ростом 1,8 м стоит на расстоянии 10 шагов от столба, на котором висит фонарь. Тень человека равна шести шагам . На какой высоте (в метрах ) расположены фонарь ?

Answer 1

X\1,8=16\6   
X=16*1,8\6=4,8

Answer 2

K=3/5 относительно маленького треугольника, длина фонаря = 1.8 * 5/3

Answer 3

Calculation of the Height of the Lamp

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

- The person is standing 10 steps away from the lamp post. - The person's shadow is 6 steps long.

We can set up a proportion to find the height of the lamp post. Let's assume the height of the lamp post is h meters.

The proportion can be set up as follows:

Person's height / Person's shadow = Lamp post height / Distance from the person to the lamp post

Using the given information, we can substitute the values:

1.8 meters / 6 steps = h meters / 10 steps

To solve for h, we can cross-multiply and divide:

1.8 * 10 = 6 * h

18 = 6h

h = 18 / 6

h = 3 meters

Therefore, the lamp post is located at a height of 3 meters.
