Question

Calculate the angles of the triangle, if they are in the ratio
2:3:4.

Answer 1

Answer:

✮We know that:

The sum of the interior angle is 180°

✮Solution:

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

According to the condition:

2x+3x+4x = 180

↦ 9x = 180

↦ x = 180/9

↦ x = 20

Therefore, The value of x is 20.

Now, The first angle is 2x = 2×20 = 40°

The second angle is 3x = 3×20 = 60°

The third angle is 4x = 4×20 =80°

$\:$

Answer 2

2x+3x+4x = 180°

↦ 9x=180

↦ x= 20

First angle = 40°

Second angle = 60°

Third angle=80°
