Question

if the angle of atriangle are in 2:3:4 what is the value of x​

Answer 1

Answer:

20

Step-by-step explanation:

It is given that the angle of triangle are in the ratio 2 : 3 : 4. Let the angles are 2x, 3x and 4x. According to the angle sum property, the sum of interior angles of a triangle is 180 degree. The value of x is 20.

Answer 2

Answer:

= x = 20

Step-by-step explanation:

Let the angle of a triangle be x.

In ratio 2 = 2 * x = 2x

3 = 3 * x = 3x

4 = 4 * x = 4x

We know that the sum of all angle of a triangle be 180°.

According to question,

2x + 3x + 4x = 180°

= 9x = 180°

= x = 180/9

= x = 20

Hence, 2x = 2 × 20 = 40

3x = 3 × 20 = 60

4x = 4 × 20 = 80

Hope it's help you.
