Question

find the angles of a trianglewhich are in the ratio 1:2:6​

Answer 1

Answer:

20, 40 and 120

Step-by-step explanation:

Let us take the values as 1x, 2x and 6x

We know the sum of the angles of a triangle are 180

So,

1x + 2x + 6x = 180

9x = 180

x = 180/9

x = 20

1x = 20

2x = 2* 20 = 40

6x = 6* 20 = 120

Therefore, the angles are 20,40 and 120

Answer 2

Answer:

Let the ratio be x

so,x+2x+6x = 180

9x = 180

x = 20

hence,x = 20

           2x = 2 * 20 = 40

          6x = 6 * 20 = 120.Ans
