Question

Напиши программу, которая вычисляет гипотенузу по двум катетам. (паскаль,все слова только на английском)​

Answer 1

Вывод, для удобства, нужно на русском, чтобы было понятно!

var a, b, c:real;

begin

writeln('Доброго времени суток! Данная программа вычисляет гипотенузу по введённым значениям катетов');

writeln('Введите длину первого катета');

readln(a);

writeln('Введите длину второго катета');

readln(b);

c:=sqrt(a*a+b*b);

writeln('В прямоугольном треугольнике с катетами  ', a, '  и  ', b, '  гипотенуза равна  ', c);

end.

Answer 2

Certainly! Below is an example of a Pascal program that calculates the hypotenuse of a right-angled triangle using the lengths of its two perpendicular sides (also known as catheti or cathetus). This program uses the Pythagorean theorem to find the length of the hypotenuse.

program CalculateHypotenuse;

uses Math;

var
  side1, side2, hypotenuse: Double;

begin
  // Input the lengths of the two catheti
  Write('Enter the length of the first cathetus (side 1): ');
  ReadLn(side1);

Write('Enter the length of the second cathetus (side 2): ');
  ReadLn(side2);

// Calculate the hypotenuse using the Pythagorean theorem: c² = a² + b²
  hypotenuse := sqrt(power(side1, 2) + power(side2, 2));

// Display the calculated hypotenuse
  WriteLn('The length of the hypotenuse is: ', hypotenuse:0:2);
end.

Here's an explanation of the program:

1. `uses Math;` - This statement enables the use of mathematical functions like `sqrt` and `power`. 2. `var side1, side2, hypotenuse: Double;` - Declares variables to store the lengths of the two catheti (`side1` and `side2`) and the calculated hypotenuse (`hypotenuse`). 3. `ReadLn(side1);` and `ReadLn(side2);` - Prompts the user to input the lengths of the two catheti. 4. `hypotenuse := sqrt(power(side1, 2) + power(side2, 2));` - Calculates the hypotenuse using the Pythagorean theorem, where `hypotenuse` is the square root of the sum of the squares of `side1` and `side2`. 5. `WriteLn('The length of the hypotenuse is: ', hypotenuse:0:2);` - Outputs the calculated hypotenuse with two decimal places.

This program prompts the user to input the lengths of the two catheti, calculates the hypotenuse using the Pythagorean theorem, and then displays the result.
