Question

The angles of a quadrilateral are in the ratio 3:4:5:6. Write a program to find and  display all of its angles. (Hint: The sum angles of a quadrilateral = 360o )

with variable description​

Answer 1

int r1 = 3, r2 = 4, r3 = 5, r4 = 6;

double x = 360 / (double)(r1 + r2 + r3 + r4);

double a = r1 * x;

double b = r2 * x;

double c = r3 * x;

double d = r4 * x;

System.out.println("Angle A = " + a);

System.out.println("Angle B = " + b);

System.out.println("Angle C = " + c);

System.out.println("Angle D = " + d);

Answer 2

Answer:

public class KboatQuadRatio

{

public static void main(String args[]) {

int r1 = 3, r2 = 4, r3 = 5, r4 = 6;

double x = 360 / (double)(r1 + r2 + r3 + r4);

double a = r1 * x;

double b = r2 * x;

double c = r3 * x;

double d = r4 * x;

System.out.println("Angle A = " + a);

System.out.println("Angle B = " + b);

System.out.println("Angle C = " + c);

System.out.println("Angle D = " + d);

}
