Question

the angles of a triangle are in the ratio 2:3:4 based on the angles it is a

Answer 1

let proportionality constant x
so, angles are 2x/9, 3x/9,4x/9
because sum of all angles of triangle is 180degree
so,
2x/9+3x/9+4x/9=180
x=180
so,
2.180/9=40
3.180/9=60
4.180/9=80
hence 40, 60, and 80 degree are the angles of triangle. because all angle are different so, this is a simple triangle which sides are different from each other.

Answer 2

Since all the angles are different therefore all the sides are different so the triangle is nothing but a scalene triangle.
