C Program to Find Area of Scalene Triangle.

C Program to Find Area of Scalene Triangle.

#include<stdio.h>

#include<math.h>

int main() {

   int s1, s2, angle;

   float area;

   printf("\nEnter Side1 : ");

   scanf("%d", &s1);

   printf("\nEnter Side2 : ");

   scanf("%d", &s2);

   printf("\nEnter included angle : ");

   scanf("%d", &angle);

   area = (s1 * s2 * sin((M_PI / 180) * angle)) / 2;

   printf("\nArea of Scalene Triangle : %f", area);

   return (0);

}

Output:-

Enter Side1 : 3

Enter Side2 : 4

Enter included angle : 30

Area of Scalene Triangle : 3.000000
