Answer 1

#include<iostream>
#include<iomanip>

using namespace std;

int main()
{
	cout<<"Radians\n Degrees\n"<<1<<endl<<setprecision(10)
	<<57.2958<<endl<<10<<endl<<fixed<<setprecision(4)
	<<572.958<<endl<<20<<endl<<1145.92<<endl<<30<<endl
	<<setprecision(5)<<1718.87<<endl<<40<<endl
	<<2291.83;
//b) We can use only 1 cout statement
/*c) I think if we use min amount of cout statements, we have a bit better performance, because of less amount of operations*/
