Question

Диагональ прямоугольника телевизионного экрана равна 58см.а высота экрана 49 см.найдите ширину экрана ответ дайти в сантиметрах

Answer 1

Ширину найдем используя формулу Пифагора:
\/58^2-49^2=\/(58-49)(58+49)= \/9·107= приблизительно 31,03 см.

Answer 2

Calculating the Width of the TV Screen

To find the width of the TV screen, 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: - Diagonal of the TV screen (hypotenuse) = 58 cm - Height of the TV screen = 49 cm

Using the Pythagorean theorem, we can calculate the width of the TV screen.

The formula for the Pythagorean theorem is: c^2 = a^2 + b^2, where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

Calculation

Let's denote the width of the TV screen as w.

According to the Pythagorean theorem: 58^2 = w^2 + 49^2

Solving for w: w^2 = 58^2 - 49^2 w = √(58^2 - 49^2)

Result

Calculating the value of w: w ≈ 35.67 cm

Therefore, the width of the TV screen is approximately 35.67 cm.
