Question

2. If angles of a triangle are in the ratio 2:3:4. Find the value of
each angle.
​

Answer 1

Answer:

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

2x+3x+4x=180(sum of angles of triangle is equal to 180 degree.

9x=180

x=180/9

x=20

1st angle = 2x

= 40

2 nd angle = 4x

= 80

3rd angle = 3x

= 60

Answer 2

Step-by-step explanation:

Sum of ratios = (2 + 3 + 4) = 9

$1st \: angle \: = \frac{2}{9} \times 180 \\ = 2 \times 20 \\ = 40$

$2nd \: angle = \frac{3}{9} \times 180 \\ = 3 \times 20 \\ = 60$

$3rd \: angle \: = \frac{4}{9} \times 180 \\ = 4 \times 20 \\ = 80$
