Question

The angles of a triangle are in the ratio 1:2:3. Find the angles.?
​

Answer 1

Answer:

30°, 60° and 90°.

Step-by-step explanation:

Let the angles be x, 2x and 3x respectively.

As we know,

sum of all angles of a triangle = 180°

So, x+2x+3x= 180°

6x=180°

x= 180°/6 = 30°.

2x= 2×30°= 60°

and 3x =3×30°= 90°

Hence, the angles are 30°, 60° and 90°.

Answer 2

Answer:

30,60,90

Step-by-step explanation:

let the first angle is x and second angle is 2x and third angle is 3x

sum of their angles are X + 2 x + 3x= 180 degree

so 6 X = 180

X 30 ( first angle)

second 2x =2 *30 = to 60

third= 3x = 3 *30 = 90
