Question

2. Write a program that prompts a user to enter the lengths of sides and angles for the two triangles described below. The program should calculate the length of the side of the triangle indicated below. Print the two answers to 3 decimal places onto the console screen Triangle 1 Read in the value of the angle, alpha, and the length, a, of the side indicated in the picture below. Calculate the length of the hypotenuse, c, of this right triangle: Test your program with: alpha 32 a-4.5 Triangle 2 Read in the value of the angle, beta, and the length, a, of the side indicated in the picture below. Calculate the length of the side opposite of the angle, b, of this right triangle: Test your program with: beta -40 a-2.2

Answer 1

/* CODE IN C */

#include<stdio.h>
#include<math.h>

int main()
{
   /*Triangle 1*/
   float alpha, a, hypotenuse;
   printf("FOR TRIANGLE 1 ");
   printf("Enter alpha = ");
   scanf("%f", &alpha);
   printf("Enter a = ");
   scanf("%f", &a);
   alpha = alpha * 3.14 / 180;//Convert beta to radians
   hypotenuse = a/sin(alpha);//Assuming a is perpendicular for alpha
   printf("Hypotenuse = %.3f ", hypotenuse);
  
   /*Triangle 2*/
   float beta, b;
   printf("FOR TRIANGLE 2 ");
   printf("Enter beta = ");
   scanf("%f", &beta);
   printf("Enter a = ");
   scanf("%f", &a);
   beta = beta * 3.14 / 180;//Convert beta to radians
   b = tan(beta) * a;//For angle beta, side a is base and side b is the opposite side
   printf("Opposite side of angle beta = %.3f ", b);
   return 0;
}

OUTPUT:

CAUsers Shubham Desktop Untitled1.exe FOR TRIANGLE 1 Enter alpha 32 Enter a4.5 Hypotenuse = 8.496 FOR TRIANGLE 2 Enter beta 40 Enter a2.2 Opposite side of angle beta 1.845 Process exited after 6.116 seconds with return value 0 Press any key to continue . . .
