Question

Three angles of a triangle are in the ratio 3 : 4:2. Find the measure of each angle
​

Answer 1

Step-by-step explanation:

Let the angles of triangle are : 3x:4x:2x

Sum of all angles of triangle is 180°

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

9x=180°

x=20°

So the 1st angle = 3x =3(20) =60°

2nd angle = 4x = 4(20) =80°

3rd angle = 2x =2(20) = 40°

Answer 2

Answer:

60:80:40

Step-by-step explanation:

3x+4x+2x=180

9x=180

180/9=x

20

3x=3 x 20 =60

4x=4 x 20 =80

2x=2 x 20 =40
