Question

The angles of a triangle are ratio 3:2:4

Answer 1

Step-by-step explanation:

let it be :-3x,2x&4x

3x+2x+4x=180

9x=180

x=180/9

x=20

angles=

3x=3*20= 60

2x=2*20=40

4x=4*20=80

Answer 2

Correct Question:

The angles of a triangle are ratio 3:2:4. Find the measurement of each angle.

Answer:

40°

60°

80°

Step-by-step explanation:

Given that, there is a triangle.

The angles of the traingle are in the ratio of :

• 2:3:4

To find the measurement of each angle.

Let the common ratio factor be x.

Therefore, the angles are,

• 3x
• 2x
• 4x

Now, we know that,

By angle sum property of a traingle,

Sum of angles = 180°

Substituting the values, we get,

=> 2x + 3x + 4x = 180

=> 9x = 180

=> x = 180/9

=> x = 20

Therefore, we will get,

=> 2x = 2×20 = 40

=> 3x = 3×20 = 60

=> 4x = 4×20 = 80

Hence, the required angles are 40°,60°and 80°.
