Question

if the angles of a triangle are in the ratio of 2:3:4 , find the all three angles​

Answer 1

Answer:

40 , 60 and 80

Step-by-step explanation:

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

Sum of all angles of triangle = 180

2x + 3x + 4x = 180

9x = 180

x = 20

Angles = 2x = 40

            = 3x = 60

            = 4x = 80

Answer 2

Step-by-step explanation:

Sum of angles in a triangle =180

angle 1 =2x

angle 2 =3x

angle 3 =4x

=2x +3x +4x =180

9x=180

x=180/9

x=20

2x=2(20)=40

3x=3(20)=60

4x=4(20)=80

Therefore the angles are 40° ,60° ,and 80° respectively.
