Step-by-step explanation:
- Let the angles be x.
- since, the angles are -
- 1x and 2x
- Now the sum of the angles is y (third side)
- Since, by angles sum property of triangle -
- 1x +2x +y =180°
- Whereas
- y = 1x + 2x
- Now put the value of y -
- 1x + 1x +2x+2x =180°
- i.e,
- 6x = 180°
- x = 30°
- Angles are -
- 30 , 60 & 90
