#includeThis code calculates the angle between the point (0.5,0.866) and the positive x-axis using the arccosine function. Both of these examples are using the#include int main() { double x = 0.5; double y = 0.866; double result = std::acos(x / y); std::cout << "The angle between (" << x << "," << y << ") and the positive x-axis is: " << result << std::endl; return 0; }
