Question

If any of traingle are in the ratio 2:3:4.find the value of each angle

Answer 1

Hey mate,

Here is your answer,

We Know that sum of angles of a triangle are equal to 180°.

Let the angles be:-

2x, 3x, 4x.

2x + 3x + 4x = 180°

9x = 180°

x = 20

Now we have to substitute the 'x' values, we get,

First angle = 2x

= 2 x 20

= 40°

Second angle = 3x

= 3 x 20

= 60°

Third angle = 4x

= 4 x 20

= 80°

Angles of the triangle are 40°, 60°, 80° respectively.

CHECK

Sum of angles = 180°

= 40 + 60 + 80

= 100 + 80

= 180°

Hope it helps:)
