Question

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

Answer 1

Answer:

First angle = 2(20) = 40°,

Second angle = 3(20) = 60°,

Third angle = 4(20) = 80°,

Step-by-step explanation:

let the angle of triangles be 2x, 3x,4x

sum of all angle of triangle= 180°

now,

2x+3x+4x=180°

9x=180°

x=180/9

x=20,

now,

First angle = 2(20) = 40°,

Second angle = 3(20) = 60°,

Third angle = 4(20) = 80°,

Answer 2

Answer:

Ratio of angles of a triangle = 2:3:4

Let, the angles be = 2a, 3a, 4a

Sum of three angles of triangle = 180 degree

So,

2a + 3a + 4a = 180

=> 9a = 180

=> a = 180/9

=> a = 20

The angles are = 2 × 20 = 40 degree

= 3 × 20 = 60 degree

= 4 × 20 = 80 degree

Ans. 40 degree, 60 degree, 80 degree

Write any two angles value from these three.
