Answer 1

Answer:

The angles are 40, 60, 80.

Step-by-step explanation:

Angle sum property of a triangle is 180degrees. It is given that the angles are in the ratio 2:3:4.

So let us consider the angles as 2x,3x and 4x.

2x+3x+4x=9x

Angle sum of triangle is 180  

so 9x=180  

or x=  20

∴,2x=2×20=40  

3x=3×20=60  

and 4x=4×20  = 80

∴ the angles are 40 ,60 ,80

Answer 2

Answer:

Here, The angles of the Triangle are 40°,60° and 80° respectively.

Step-by-step explanation:

1)=Here,As per our given question,

=Let the given ratio of angle be with x

So, As we know that the sum of the angles of a triangle is 180°

So, 2x+3x+4x=180°

=9x=180°

=x=180/9

=x=20

Now, As we supposed, put the value of x,

=2x=2×20=40°

=3x=3×20=60°

=4x=4×20=80°

So, here The angle of the Triangle are=40°,60° and 80° respectively.

2)=Incomplete question.
