QUESTION:-
In(triangle)ABC,(angle)C =3(angle)B=2(angles)A+B,(angle)B=?

Also given that,

Also given that,∠C=3∠B and 3∠B=2∠A+2∠B

Also given that,∠C=3∠B and 3∠B=2∠A+2∠B∠A=2∠B

Substituting values in (1), we get

Substituting values in (1), we get∠B/2+∠B+3∠B=180∘

∴∠B=40∘

∴∠B=40∘    ∠A=20∘

∴∠B=40∘    ∠A=20∘    ∠C=120

the correct answer is the second option

are you an artist's daughter? cuz dang you a fine piece of art, girl.
