Question

of the three angles of a triangle, one is twice the smallest and another is three times the smallest .find the angles

Answer 1

Let the smallest angle be x.
let the angles be x, 2x and 3x.

sum of angles. = 180

x+2x+3x = 180
6x = 180
x = 30

the angles are 30,60,90

Answer 2

Let the smallest angle be x
Then another angle is 2x
then 3rd angle is 3x
The sum of angles of triangle add up to 180°
A.T.P.,
      x+2x+3x=180
     ⇒6x=180
     ⇒x=180/6=30

First angle =30° 
Second angle= (30×2)°=60°
Third angle=(30×3)°=90°
