Answer:-
⠀⠀⠀⠀⠀⠀⠀⠀⠀According to the Question
Let the ratio of angle of triangle be x : 2x : 3x
As we know that sum of all angles in triangle is 180°
Substitute the value we get
x + 2x + 3x = 180°
3x+3x = 180°
6x = 180°
x = 180°/6
x = 30°
So the value of x = 30°
Now , putting the value
x = 30°
2x = 2×30 = 60°
3x = 3×30° = 90°
- Hence, the angles of the triangle is 30° , 60° & 90° respectively.
Since , one angle is 90°
So ,the triangle is Right Angle Triangle .
