sum of all the angles in a triangle is 180°

x+2x+3x=180°

6x=180°

x=180°/6

x=30°

Now,the angles are x=30°

2x=2(30°)=60°

3x=3(30°)=90°

Therefore,

**the smallest angle is 30°**

=6x

total=180

6x=180

x=180/6

=30

angle 1=1*30 = 30

angle 2 = 2*30 = 60

angle 3 = 3*30 = 90

so, the smallest among them is 30 degree angle
