Question

the three interior angles of the triangle are in the ratio 3:4:2 find the measures of these angles​

Answer 1

Answer:

let the angles are 3x, 4x ,2x.

sum of angles = 180.

3x+4x+ 2x = 180

9x = 180

x = 180/9 = 20.

3x = 3× 20 = 60

4x = 4× 20 = 80

2x = 2× 20 = 40

60+80+40 = 180.

Answer 2

Answer:

ratio = 60:80:40

Step-by-step explanation:

we know sum of all interior angles = 180°

so ratio = 3x;4x:2x

3x+4x+2x = 9x

9x =  180°

x = 180/9

x = 20°

3x = 3x20 = 60°

4x = 4x20 = 80°

2x = 2x20 = 40°

so ratio = 60:80:40
