Question

the angles of triangle ABC are in the ratio angleA: angleB : angleC=1:2:3. find the magnitude of each angle.​

Answer 1

Answer:

The angles are 30°, 60°, 90°.

Step-by-step explanation:

The angles of a triangle always have a sum of 180°.(Angle sum property)

As given , the ratio is 1:2:3 ,We have ,

1x + 2x + 3x = 180°

Now compute x and put it equal to 180°.

as we have,

6x = 180°

x = 180/6

x = 30°

As we have the ratio 1:2:3,

1x= 30°

2x= 2×30 = 60°

3x = 3×30 = 90°

Answer 2

Answer:

30° 60° 90° ...........
