Sivan’s is teaching his son Vigneshwaran his daily lessons in their home. Vigneshwaran’s mathematics homework note had a question named Mad angles where he need to check if some angles are given it is valid one to form a triangle.

To make his son understand the problem sivan panned to write a simple programming logic for the same.

Functional Description:

The angles are valid to form a triangle if:

Sum of all three angles are equal to 180 degree as well as angle1, angle2 and angle3 > 0

#include <stdio.h> int main() { int angle1,angle2,angle3,sumofangles; scanf("%d%d%d",&angle1,&angle2,&angle3); sumofangles=angle1+angle2+angle3; if(sumofangles==180){ printf("Angles are valid"); } else{ printf("Angles are not valid"); } return 0; }

**INPUT_1:**

90

55

35

**OUTPUT:**

Angles are valid

**INPUT_2:**

67

49

54

**OUTPUT:**

Angles are not valid
