Q-9.Write a C Program to input two angles from user and find third angle of the triangle. How to find all angles of a triangle if two angles are given by user using C programming. C program to calculate the third angle of a triangle if two angles are given.

1. #include<stdio.h>
2. #define SUM 180
3. int main(){
4.   //1
5.   float firstAngle,secondAngle,thirdAngle;
6.   //2
7.   printf("Enter first and second angle of the triangle : ");
8.   scanf("%f %f",&firstAngle,&secondAngle);
9.   //3
10.   thirdAngle = SUM - (firstAngle + secondAngle);
11.   //4
12.   printf("You have entered %f and %f\n",firstAngle,secondAngle);
13.   printf("Third Angle is : %f \n",thirdAngle);
14.   return 0;
15. }
