Answer 1

Answer:

Explanation:

Source code:

#include<iostream>

using namespace std;

int main()

{

int angle1,angle2,angle3;

cout<<"Enter the three angles of triangle:";

cin>>angle1>>angle2>>angle3;

if (angle1+angle2+angle3==180)

 cout<<"Triangle is valid";

else

 cout<<"Triangle is not valid";

 

return 0;

}

Output

SAMPLE RUN # 1

Enter the three angles of triangle:60 50 50

Triangle is not valid

SAMPLE RUN # 2

Enter the three angles of triangle:60 90 30

Triangle is valid
