Question

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

Answer 1

По теореме Пифагора.
17^2=x^2+8^2
x^2=225
x=15см

Answer 2

Calculating the Second Side of a Rectangle

To find the second side of the rectangle when one side is 8 cm and the diagonal is 17 cm, 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.

Using the Pythagorean theorem:

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), and a and b are the lengths of the other two sides.

Given: - One side of the rectangle, a = 8 cm - The diagonal of the rectangle, c = 17 cm

We can solve for the second side, b, using the Pythagorean theorem.

Calculation: - c^2 = a^2 + b^2 - 17^2 = 8^2 + b^2 - 289 = 64 + b^2 - b^2 = 289 - 64 - b^2 = 225 - b = √225 - b = 15

Answer: The second side of the rectangle is 15 cm.
