Question

In the figure given triangle ABC . Also , find triangles ABC if triangle C=3 triangle ABC​

Answer 1

Answer:

the sum of all the interior angles is 180∘

⇒ ∠A+ ∠B+ ∠C= 180∘........(1)

Also given that,

3∠B=

2∠A+

2∠B

∠C= 3∠B

∠A= 2

∠B

Substituting values in (1), we get

2

∠B

+ ∠B+ 3∠B= 180∘

∴ ∠B= 40∘

∠A=20∘

∠C=120∘
