Question

In all the three angles of the triangle are in ratio 2x ratio 3 ratio 4 then find the value of each angle? ​

Answer 1

$\bold{Answer}$

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

A rule,

All the angles of a triangle when added together result in 180° . i.e. ,

∠A + ∠B + ∠C = 180°

According to the question,

2x + 3x + 4x = 180°

9x = 180°

x = 20°

So, angle a which is 2x will be,

2x = 2 × 20 = 40°

Angle B,

3x = 3 × 20 = 60°

Angle C ,

4x = 4 × 20 = 80°

Answer 2

Step-by-step explanation:

let the no be =3x,4x&2x

180=2x+3x+4x

180=9x

180÷9=x

20=x

now, put the value

2x=2×20

=40

3x=3×20

=60

4x=4×20

=80

40+60+80=180

1angle=40

2angle=60

3angle=80

I hope this will help you
