Question

The angles of a triangle ABC are 2x,3x and 4x .Find the angles of the triangle

Answer 1

2x+3x+4x=180 degree

9x=180 degree

x=180/9

x=20 degree

2x= 2x20=40 degree

3x=3x20=60 degree

4x=4x20=80 degree

Answer 2

hope this helps u

given :-

angles are 2x,3x,4x

to find

value of x

solution

we know angle sum property of a triangle

according to it

all angles sum upto 180

so

angle a+ angle b +angle c = 180

we will enter values

2x+3x+4x=180

9x= 180

x = 20

2x= 2*20 = 40

3x= 3*20 = 60

4x = 4*20=80

verification

40+60+80 = 180

180=180
