Question

Одна из сторон прямоугольника равна 8 см,а диагональ 17 см. Чему равна вторая сторона прямоугольника?

Answer 1

17см.Потому что диагональ чертится края угла до другой не соседнего для не него угла.

Answer 2

Calculating the Second Side of a Rectangle

To find the second side of the rectangle, 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.

Given: - One side of the rectangle = 8 cm - Diagonal of the rectangle = 17 cm

Using the Pythagorean Theorem

We can use the Pythagorean theorem to find the length of the second side of the rectangle.

The formula for the Pythagorean theorem is: c^2 = a^2 + b^2

Where: - c is the length of the hypotenuse (the diagonal of the rectangle) - a and b are the lengths of the other two sides of the right-angled triangle

Calculation

Using the given values: - One side of the rectangle (a) = 8 cm - Diagonal of the rectangle (c) = 17 cm

We can solve for the second side (b) using the Pythagorean theorem: b^2 = c^2 - a^2

Substituting the given values: b^2 = 17^2 - 8^2 b^2 = 289 - 64 b^2 = 225

Taking the square root of both sides: b = √225 b = 15

Answer

The second side of the rectangle is 15 cm.
