Question

Угол С = 90 градусов АС = 420 м СВ = 560 м АВ - найти P.S. В ответе 700 должно выйти

Answer 1

AC+CB= 1000м
1000м-300(площадь всех сторон)= 700м

Answer 2

Calculation of the Length of AB

To find the length of AB, we can use the Pythagorean theorem. The Pythagorean theorem states that in a right 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.

In this case, we have a right triangle with AC as one of the legs and BC as the other leg. The hypotenuse is AB.

Given: - Angle C = 90 degrees - Length of AC = 420 m - Length of BC = 560 m

Using the Pythagorean theorem, we can calculate the length of AB as follows:

AB^2 = AC^2 + BC^2

Substituting the given values:

AB^2 = (420 m)^2 + (560 m)^2

Calculating:

AB^2 = 176,400 m^2 + 313,600 m^2

AB^2 = 490,000 m^2

Taking the square root of both sides to find AB:

AB = √(490,000 m^2)

AB ≈ 700 m

Therefore, the length of AB is approximately 700 meters.

P.S. In the answer, the value of 700 should be obtained.
