Question

the angles of a triangle are in the ratio 1:2:3. find the angles

Answer 1

1x+2x+3x=180 (as total sum of the angles of a triangle is 180)
6x=180
x=30
1st angle =30*1=30
2nd angle =30*2=60
3rd angle =30*3=90

Answer 2

1x+2x+3x=180 (sum of the all angles of a triangle is 180)
6x=180
x=30
1st angle =30*1=30
2nd angle =30*2=60
3rd angle =30*3=90
