Question

the angles of a triangle are in the ratio of 2 . 3. 4. f d the measure of each angle of the triangle​

Answer 1

Let , the common ratio be x

Then , the angles of the triangle be 2x , 3x and 4x

•°• 2x + 3x + 4x = 180°

9x = 180°

x = 180° / 9

x = 20°

•°• The angels are 40° , 60° and 80°

Answer 2

let the angles be 2x 3x 4x

sum of all angles =180

2x+3x+4x=180

9x=180

x=20

2x=2(20)=40

3x=3(20)=60

4x=4(20)=80
