Let's denote the smallest angle as X degrees. Then the other two angles are 2X and 3X.
X + 2X + 3X = 180
6X = 180
X = 30
It is a 30, 60, 90 triangle
X + 2X + 3X = 180
6X = 180
X = 30
It is a 30, 60, 90 triangle

Given: The angles are in the ratio 1:2:3.
To find: The angles.
Answer:
Let the angles be 1x, 2x and 3x.
1x + 2x + 3x = 180° (Angle Sum Property)
6x = 180°
x = 180°/6
x = 30°
Therefore, the angles are 1x = 1*30 = 30°, 2x = 2*30 = 60° and 3x = 3*30 = 90°.
Hope it helps :)
