Question

Мальчик прошёл от дома по направлению на восток 40 метров, затем повернул на север и прошёл 30 м. На каком расстоянии от дома мальчик? Можно с решением

Answer 1

40+30=70
70-40=30
это и есть твой ответ

Answer 2

Теорема Пифагора или же египетский треугольник
Катеты это 40 и 30 метров , а расстояние от дома - гипотенуза , соответственно 50м:)

Answer 3

Solution:

The boy first walked 40 meters to the east and then turned north and walked 30 meters. To find the distance from the starting point to the final position, we can use the Pythagorean theorem, which states that in a right-angled triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.

Using this theorem, the distance from the starting point to the final position can be calculated as:

Distance = √(40^2 + 30^2)

Distance = √(1600 + 900)

Distance = √2500

Distance = 50 meters

So, the boy is 50 meters away from his starting point.

Explanation:

The boy's movement can be visualized as a right-angled triangle, with the eastward movement representing one side and the northward movement representing the other side. The distance from the starting point to the final position is the length of the hypotenuse of this triangle, which can be calculated using the Pythagorean theorem.

Additional Information:

The Pythagorean theorem is a fundamental principle in geometry and is named after the ancient Greek mathematician Pythagoras. It is used to calculate the length of the sides of a right-angled triangle and has applications in various fields, including mathematics, physics, and engineering.
