Question

the angels of a triangle are in the ratio 2 : 3 : 4. find the angles
​

Answer 1

Answer:

The angles are 40° , 60° , 80° .

Step-by-step explanation:

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

Sum of angles of a triangle = 180°

2x+3x+4x = 180°

9x = 180°

x = 180°\9

x = 20°

Angle 2x = 2x20° = 40°

Angle 3x = 3x20° = 60°

Angle 4x = 4x20° = 80°

Sum of all the angles of a triangle = 180°

40°+60°+80° = 180°

Answer 2

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

= 2x+3x+4x=180..

=5x+4x=180..

=9x=180

x=180/9

x=20..

The angles are - - - - - - - 2=2*20=40...

3=3*20=60

4=4*20=80

The angles are 40,60,and 80..

Hope it help
