Considering the angle a by cosine rule
11^2 =7 ^2 +15^2 - 2(7)(15)cos(a)
When you do the maths,
Cos(a) =153/210 =0.729
a= cos inverse of 0.729
a=43 degrees
Considering angle b
7^2=15^2 +11^2 -2(11)(15) cos(b)
This will result in cos(b) =297/330=0.9
b= cos inverse of 0.9 = 25.8 degrees
Considering angle c
15^2=7^2 +11^2 - 2(11)(7) cos(c)
Cos(c) will be = -55/154 = -0.357
c= cos inverse of -0.357=110.9
Comparing the angles a,b and c,
C is the largest size in the triangle with an angle of 110.9 degrees

The function that takes three decimal numbers as inputs and finds the sum of those inputs and returns the sum has been given below
What is programming?
Program is the set of instructions given to the computer so that the computer can execute those instructions. The act of writing program is called programming.
The program has been shown below
#include<stdio.h>
using namespace std;
int main()
{
double n1, n2, n3;
double s;
printf("Enter first numbers");
scanf(%lf, &n1);
printf("Enter second numbers");
scanf(%lf, &n2);
printf("Enter third numbers");
scanf(%lf, &n3);
s = n1 + n2 + n3;
printf("Sum = %f", s);
return 0;
}
