Question

Find the angles of a triangle which are in the ratio 1:2:3.

Answer 1

Answer:

30,60 and 90

Step-by-step explanation:

3+2 + 1 = 180

6=180

1=30

2 = 60

3 = 90

Answer 2

The angles are 30° , 60° , 90°

Step-by-step explanation:

GIVEN :

Angles are in the ratio 1:2:3

We know that , sum of angles in a triangle equals 180° { Angle sum property }

Let the angles be 1x ,2x ,3x

By angle sum property,

1x + 2x + 3x =180°

6x = 180°

x = 180/6

x = 30 °

Substituting the value of x,

1 x = 30°

2x = 2(30) = 60°

3x = 3 (30) = 90°

Therefore the angles are 30° , 60° , 90°
