Question

Мальчик прошёл от дома по направлению на восток 15 м. Затем повернул на север и прошёл 30 м. На каком расстоянии ( в метрах ) от дома оказался мальчик? ​

Answer 1

Объяснение:

$\sqrt{30 {}^{2} + 15 {}^{2} } =15 \sqrt{5} = =33.5$

Answer 2

Calculating the Distance from Home

To calculate the distance from home, we can use the Pythagorean theorem, which states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

Let's denote the distance traveled east as 15 m and the distance traveled north as 30 m.

Using the Pythagorean theorem, the distance from home can be calculated as:

Distance from home = √(15^2 + 30^2)

Distance from home = √(225 + 900)

Distance from home = √1125

Distance from home ≈ 33.54 m

So, the boy was approximately 33.54 meters away from home.
