Question

If the angles in a triangle are in the ratio 1 : 2 : 3 then find all the angles of a triangle.​

Answer 1

Answer:

angle 1 (A) = 1x

angle 2(B) = 2x

angle 3(C) = 3x

A+B+C = 180°

1x+2x+3x = 180°

6x=180°

x=180/6

x=30

A= 1×30 = 30

B= 2×30= 60

C= 3×30 = 90

Answer 2

Answer:

let the ratio be x.

then,

it's angles are -

1x , 2x, and 3x

now,

1x+2x+3x = 180° ( sum of angle of triangle is 180°)

6x = 180°

x= 180°/6

x = 30°

therefore measure of its angles are

1x = 30°

2x= 2 x 30°= 60°

3x= 3 x 30° = 90 °
