Question

find the angle of a triangle they are in the ratio 2:3;4​

Answer 1

Answer:

If the angles of a triangle are in the ratio of... 2 :3 :4 then we can divide the Total Degrees of the Triangle i.e 180 degrees in that order as below : 2+3+4 = 9 Parts of 180 is … 180/9 = 20 degrees.

2*20=40 degrees.

3*20=60 degrees.

4*20=80 degrees.

Answer 2

Answer:

40, 60, 80

Step-by-step explanation:

Ratio of angles = 2:3:4

So let the angles be $2x$, $3x$ and $4x$.

According to the Angle Sum Property of Triangles,

Sum of all angles of a triangle is equal to 180 degree.

So,

$2x + 3x + 4x = 180$

$9x = 180$

$x = 180/9$

$x = 20$

So, the angles are

$2x = 2(20) = 40\\3x = 3(20) = 60\\4x = 4(20) = 80$

The angles are 40, 60 and 80 degrees.
