Three angles are = 40°, 60°, 80°
Step-by-step explanation:
Given:-
- Ratio of angles of a triangle = 2 : 3 : 4
To Find:-
- Find all the angles of triangle
Ratio of angles of a triangle = 2 : 3 : 4
Therefore, First angle = 2X
==> Second Angle = 3X
==> Third angle= 4X
We know that the sum of all interior angles of a triangle is 180°
Therefore, 2X + 3X + 4X = 180°
==> 9X = 180
==> X = 180/9
==> X = 20°
Now,. First angle = 2X = 2 × 20=40°
==> Second Angle = 3X = 3 × 20 = 60°
==> Third angle = 4X = 4 × 20= 80°
