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;
}

Answer: The measure of angle 3 is 50 degrees.
Step-by-step explanation:
We know that angle 2 is 130 degrees.
Angle 1 and angle 2 are verticle angles which means that they are across and equal to each other.
So angle 1 and angle 2 are 130 degrees.
Add up both angle 1 and angle 2, 130 + 130 = 260.
Now, all of these angles add up to be 360 degrees in total as they make a circle and there are 360 degrees in one.
Subtract 260 from 360, 360 - 260 = 100.
Since both angle 3 and angle 4 are also verticle angles we need to split the 100 degrees evenly, 100 ÷ 2 = 50.
So, angle 3 is 50 degrees.
