Question

In triangle abc, bc is produced to d angle a:angle b:angle c= 3:2:1

Answer 1

(According to the given diagram)

Answer:

a=90°

b=60°

c(interior one)=30°

d(exterior angle c)=150°

Step-by-step explanation:

a:b:c=3:2:1

let c be x

thus,

b=2x,c=3x

3x+2x+x=180°

=>6x=180°

=>x=30°

a=3x=90°

b=2x=60°

c=x=30°

d=180°-30°

=150°
