Question

9. The sides of a triangle
are in the ratio 3:2:1. Show that the triangle is right angled.​

Answer 1

we know sum of 3 angles = 180°

3x + 2x + 1x = 6x

6x = 180

x = 180 /6

x = 30°

Now finding the 3 angles

3 × 30 = 90°

2 × 30 = 60°

1 × 30 = 30°

So angles are 90° , 60° and 30°

Answer 2

Answer:

We know,

Sum of three angles = 180°

3x+2x+1=6x

6x = 180

X = 180/6

X = 30°

we have to find 3 angles so,

3×30 = 90°

2×30 = 60°

1×30 = 30°

So,the angles are 90°,60,°30°
