Question

The ratio of angles in a triangle is 1:2:3. Find all angles

Answer 1

Step-by-step explanation:

Let the ratio be 1x:2x:3x

A.T.Q

1x + 2x + 3x = 180°

6x=180°

x=180°/6

x=30°

1x =1x30°=30°

2x =2x30°=60°

3x =3x30°=90°

Answer 2

sum of all angles of triangle is 180.

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

1x+2x+3x=180

6x=180

x=180/6

x=30

1 angle=1x=1×30=30

2 angle=2x=2×30=60

3 angle=3x=3×30=90

Hence the angles of triangle are 30,60 and 90.
