You can put this solution on YOUR website! angle of triangle are 3x ,2x-7 ,4x-11
as per property of triangle
the sum of all three angles are 180 degree
3x+2x+4x-7-11=180
9x-18=180
9x=180+18
9x=198
x=198/9
x=22 degree
1st angle 3x=3x22=66
2nd angle 2x-7 2x22-7=37
3rd angle 4x-11=4x22-11=77
Answer 66 degree
37 degree
77 degree
