Question

the angles of triangles are in the ratio 1:2:3 then the least angle is​

Answer 1

Answer:

10° is the correct answer

Answer 2

Answer:

30°

Step-by-step explanation:

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

we know that angle of a triangle is 180°

according to the question :

1x+2x+3x = 180°

6x = 180°

x = 180/6

x = 30°

therefore, the angles are :

1x = 30°

2x = 60°

3x = 90°

least angle = 30°
