Question

write a program to find a side of a right angled triangle whose two side and an angle is given ​

Answer 1

If the given side is an even number, then find (N^2)/4. The integer before and after this value will make a right angled triangle. Example, if 8 is the given side, then (8^2)/4 = 16. So the other two sides of the right angled triangle will be 15 and (edit)17.

[Thank you Saddam for correcting me]

Now if the given side is an odd number, then find (N^2)/2. Here also, the integers before and after the found out value will make the right angled triangle. For example, if 3 is the number. Then (3^2)/2 = 4.5 So the other two sides will be 4 and 5.

Answer 2

// C++ implementation of the approach  

#include<bits/stdc++.h>  

#include <iostream>  

#include <iomanip>  

using namespace std;  

 

// Function to return the hypotenuse of the  

// right angled triangle  

double findHypotenuse(double side1, double side2)  

{  

   double h = sqrt((side1 * side1) + (side2 * side2));  

   return h;  

}  

 

// Driver code  

int main()  

{  

   int side1 = 3, side2 = 4;  

   cout << fixed << showpoint;  

   cout << setprecision(2);  

   cout << findHypotenuse(side1, side2);  

}
