Write a C program to find angles of a triangle if two angles are given

• In this program, we declare three float variables angle1, angle2, and angle3. We use printf() and scanf() to get the values of the first two angles from the user.
• We then calculate the value of the third angle using the formula angle3 = 180 - (angle1 + angle2) since the sum of the angles in a triangle is always 180 degrees.
• Finally, we print out the value of the third angle using printf(). Note that we use the %f format specifier to print out the floating point value of the angle.

#include <stdio.h>

int main() {
   float angle1, angle2, angle3;

   // Get the first two angles from the user
   printf("Enter the first angle of the triangle: ");
   scanf("%f", &angle1);
   printf("Enter the second angle of the triangle: ");
   scanf("%f", &angle2);

   // Calculate the third angle
   angle3 = 180 - (angle1 + angle2);

   // Print the third angle
   printf("The third angle of the triangle is %f degrees\n", angle3);

   return 0;
}

OUTPUT

Enter the first angle of the triangle: 60
Enter the second angle of the triangle: 70
The third angle of the triangle is 50.000000 degrees
