Question

The interior angles of a triangle are in the ratio 1:2:3, then the ratio
of its exterior angles is​

Answer 1

Ratio of interior angles =1:2:3  

Let the angles are x,2x,3x  

x+2x+3x=180

6x=180

So,

x=30

2x=60

3x=90

let, exterior angle be a,b,c.

a=360−30

a=330

b=360−60

b=300

c=360−90

c=270

a:b:c=330:300:270

a:b:c=11:10:9
