Write a program that prompts the user for the lengths of the two legs of a right triangle, and which reports the length of the hypotenuse. recall that the hypotenuse length satisfies the formula:
c =√ (a² + b²)

The following code is in c++

#include <iostream>

#include<math.h>

using namespace std;

int main()

{

   float a,b,c;

   cout<<"Enter height and base of triangle\n";

   cin>>a>>b;  //reading two sides from user

   c=sqrt(pow(a,2)+pow(b,2));  //calculating hypotenuse

   cout<<"Length of hypotenuse is "<<c;  //printing third side of triangle

   return 0;

}

OUTPUT :

Enter height and base of triangle                                                                                            

3                                                                                                                              

4                                                                                                                              

Length of hypotenuse is 5  

Explanation:

In the above code, three variables a, b and c of int type are declared. After that, it is asked from user to enter the value of a and b. The user puts the value and then c is calculated with the help of Pythagoras theorem formulae which squares the values of two sides and then adds them to calculate hypotenuse of a right angled triangle and finally c is printed to console.

browsing like internet search? don't look at anything stupid. or set up restrictions on ur device's search engine. and if something suspicious comes up don't be dumb and click on it. i hope that's what ur question meant.
