Question

6th sum with all steps please no direct answers urgently

Answer 1

Let the angles be,
2x,3x,4x

we know that sum of interior angles of a triangle is 180

so,

2x+3x+4x=180

9x = 180

x = 180/9 =20

so angles are

2x = 2×20 =40
3x= 3×20 =60
4x = 4 ×20=80

angles are 40°,60°,80,°

Here all the angles are different so the triangle is scalene triangle
