Question

The sides AB, BC and CA of a triangle ABC are produced. It is found that exterior angle c is greater than exterior angle b is greater than exterior angle a. Write the sides in ascending order of magnitude.

Answer 1

Answer:

It's proved

Step-by-step explanation:

x+y+z=180

x+∠BAE=180∘

y+∠CBF=180∘

z+∠ACD=180∘

(x+y+z)+∠BAE+∠CBF+∠ACD=540∘

∠BAE+∠CBF+∠ACD=540−180=360∘
