let the angles of triangle be x
Now, According to the question
2x + 3x + 4x = 180 (Angle sum property)
9x = 180
x = 180/9
x = 20
So the smallest angle is 2(20) => 40 Degree

Given:
- The angles of a triangle are in the ratio 2:3:4.
To find:
- The size of its smallest angles
Solution:
❍ Let the angles of the triangle be 2x, 3x and 4x
We know that,
Hence,
- First angle = 2x = 2 × 20 = 40°
- Second angle = 3x = 3 × 20 = 60°
- Third angle = 4x = 4 × 20 = 80°⠀
⠀
So, The size of smallest angles = 40°
