Question

The ratio of the measures of the three angles of a traingle is 2:3:4.find the measure of the largest angle

Answer 1

Step-by-step explanation:

let the angles be 2x 3x and 4x

then, 2x+3x+4x=180

==> 9x=180

==> x = 180/9 = 20

•°• Lenght of largest side = 4×20 = 80

Answer 2

Answer:

The sum of the angles of a triangle is 180 degree.

Let the measure of an angle be x.

Automatically, the equation will be

2x + 3x + 4x = 180

9x = 180

x = 180/9

x = 20

So,

2x = 2 x 20

    = 40

3x = 3 x 20

    = 60

Therefore the measure of the largest angle which is 4x will be,

 4x = 4 x 20

      = 80

The measure of the largest angle is 80 degree.
